### 1/5 — It won’t let me play the game

*2026-08-25, version 1.25.5*

It won’t work

### 5/5 — propose

*2026-08-19, version 1.25.4*

Hello, I'm a long-time player and I really love this game. Here are some suggestions for future updates:

【Traffic Environment Enhancement】
1. Rush Hour Mode: Increase traffic volume and congestion during specific time periods to simulate real commuting experiences.
2. Holiday Crowds: Add more pedestrians crossing streets near shopping districts and tourist spots, requiring drivers to proactively slow down.
3. Traffic Violation AI: Introduce jaywalking, running red lights, and sudden "ghost sightings" to increase driving tension.
4. Random Unexpected Events: Sudden braking ahead, doors opening from parked cars, blowouts, etc., to test reaction ability.

【New Vehicle Models】
1. Multiple large-capacity articulated buses, simulating the real feel of the trailer section following during turns.
2. Three-axle city buses.
3. High-capacity urban buses.
4. Tourism coaches and long-distance intercity buses.

【Vehicle Size & Model Coverage】
Vehicles should cover the following lengths to form a complete product line:
- 25m articulated buses (e.g., BRT high-capacity buses)
- 18m articulated buses
- 16m articulated buses
- 13.7m three-axle city/suburban buses
- 12m standard city buses
- 10m mid-size buses
- 8m compact buses

Vehicles from 25m to 16m should be articulated, and 13.7m models should be three-axle. The articulated bus lineup should include hybrid and fully electric variants. Also consider adding hybrid double-decker buses and fully electric double-decker buses.

Articulated buses should simulate the real feel of the trailer section following during turns, and three-axle vehicles should have rear-wheel steering.

【Vehicle Door Configuration】
1. Buses should have front and rear doors — front door for boarding, rear door for alighting — simulating real passenger flow.
2. Articulated buses can add a middle door to accommodate higher passenger capacity.

【Scheduling & Dispatch System】
1. Add a scheduling mechanism: after starting a shift, the system assigns specific vehicles and routes.
2. Multiple route types: long-distance routes / short-distance routes / bus routes / tourism charters / regular inter-provincial routes.
3. Curb stop mechanism: routes without depots require vehicles to wait at designated curbside stops and depart on schedule.
4. After service, vehicles return to the depot for refueling/recharging, forming a complete operational loop.

【Hybrid System Details】
Add customizable hybrid power systems (especially for buses), allowing drivers to switch freely during operation:
1. Hybrid type selection: PHEV (plug-in hybrid), SHEV (series hybrid), CHEV (parallel hybrid) — all three supported, with noticeable differences in power response and fuel efficiency.
2. Mode switching: pure electric / hybrid / fuel-priority, switchable anytime during operation.
3. PHEV power distribution: allow setting the threshold speed (e.g., 20 km/h) at which the electric motor disengages and the engine kicks in.
4. Startup method: drivers can choose between pure electric start or engine start.

These hybrid strategy elements will add depth and realism to the driving experience.

【Fuel/Power Types & Vehicle Ratio】
1. Diverse power types:
   - Pure diesel
   - Pure LNG
   - Pure CNG
   - Fully electric
   - Hybrid (PHEV/SHEV/CHEV)

2. Vehicle ratio: hybrid and fully electric vehicles should be prioritized to reflect the current trend of bus electrification. Diesel, CNG, LNG, and LPG vehicles can be included as supplementary options.

3. Corresponding refueling/charging facilities:
   - Diesel gas stations
   - CNG filling stations
   - LNG filling stations
   - LPG filling stations
   - Charging piles / battery swap stations

4. After operation, vehicles should return to the depot for refueling/charging. Running out of energy should affect normal operation.

【Speed Control & Gear Optimization】
1. Precise speed control: the 20-40 km/h low-speed range should allow stable speed control, preventing the vehicle from automatically accelerating.
2. Low-speed gear: add a low gear for slow maneuvering in garages, narrow roads, and congested areas.
3. Crawling gear (climbing gear): simulate downshifting for buses climbing long uphill sections on highways.
4. Linear throttle/brake response: improve acceleration and braking sensitivity for finer speed control.

【Suspension Adjustment System】
1. Add suspension height adjustment for buses.
2. Drivers can manually raise or lower the vehicle height based on road conditions — lower for boarding/alighting, raise when going over speed bumps or slopes to protect the chassis.

【Driving Feel Optimization】
1. Bus steering wheel should have a 2.5-turn rotation range, closer to real driving.
2. Three-axle vehicles should have rear-wheel steering — rear wheels should also turn during cornering.
3. Manual transmission vehicles should have a stall mechanism: the engine stalls if the clutch is released too quickly or the gear is mismatched, requiring a restart.

These features would not only enhance the gaming experience but also help bus enthusiasts and aspiring drivers familiarize themselves with real vehicle operations — both practical and fun.

Looking forward to future updates. Thank you!

### 5/5 — Pls send me the car

*2026-08-14, version 1.24.3*

I liked and subscribed to the creator of this game but I didn’t get the car pls send me it

### 4/5 — .

### 2/5 — Car

*2026-08-12, version 1.24.3*

In my game there is no update you have to fix it

### 4/5 — Bug!

*2026-08-10, version 1.24.3*

Overall good game but there is a bug with the Mercedes gift car. The bug is that when you accelerate the car turns randomly!? Please fix, thank you!

### 5/5 — propose

*2026-08-07*

Hello, I think you have done a very good job in this game. I have a few suggestions that I hope will be adopted. First of all, the MAN double-decker bus has some rear-wheel steering, otherwise it is not easy to turn around, and it will grind tires, and the sound is very uncomfortable. Second, the game can set up some pure electric, hybrid or gas hinge pick-up cars, hybrid buses Cars, etc., plus the scene of morning and evening rush hours, and the scene of electric bicycles driving on non-motorized lanes will be more realistic. I think your game will get better and better, thank you. The steering wheel of buses, buses and trucks can be changed to two and a half or three laps. I hope it will be adopted, thank you

### 5/5 — Subject: Full-screen ad close (X) button freezes UI on iPadOS 26.6 (iPad 10th gen), same build works

*2026-08-07, version 1.24.3*

Hi team,
On iPad (10th generation), iPadOS 26.6 (23G71), your app 𝟹𝙳 𝙳𝚛𝚒𝚟𝚒𝚗𝚐 𝙶𝚊𝚖𝚎 𝟺.𝟶 (current App Store version, same build number as on iPhone) shows a full-screen ad. Behavior:
* Tapping Skip on the video works and pauses/hides the creative.
* After Skip, the ad view controller is NOT dismissed; the screen stays on the ad layer.
* Tapping the close (X) button draws a gray highlight box around the button, then the entire UI main thread freezes. Game audio keeps playing (audio thread alive), but all touch input is dead. Only force-quitting the app from App Switcher restores it.
* The same app version on iPhone (same iOS 26.6) dismisses the ad normally via the X button. No freeze.
This matches a known iOS 26 issue where adDidDismissFullScreenContent / the dismissViewControllerAnimated:completion: chain does not fire on iPad window/scene life-cycle (multi-window, Stage Manager, Liquid Glass), causing the ad SDK to deadlock on the main thread while destroying its WebView.
Steps to reproduce on iPad:
1. Open app, trigger a full-screen rewarded/interstitial ad.
2. Wait for Skip, tap Skip.
3. Tap the X close button.
4. Gray box appears, UI frozen, audio continues.
Expected: X dismisses the ad VC and returns to the app.
Actual: Main thread deadlock, must force-quit.
Please adapt the ad presentation/dismiss path to iPadOS 26 UIWindowScene (set GADRequest.scene / present from the correct windowScene.rootViewController, avoid sync WebView teardown on the main thread after non-interactive dismiss).
Thanks.

It won’t work

### 5/5 — 눈 한쪽 감고 보면 서울과 거의 똑같이생긴 맵

*2026-08-04*

초등학교 저학년때 매우 하고싶던 게임이었는데 아이폰이라 못하다가 앱스토어에 있다는것을 뒤늦게 알고 잘 하고있습니다. 서울을 구현한 퀄리티는 굉장히 높습니다. 그래픽이라든지, 커스텀, 도색부분에서는 3D운전교실보다 한수 위인것같기도 하고요. 하지만 겉은 화려하지만 안은 비어있는 게임입니다. 경부고속도로를 타다보면 시공으로 떨어지고, 허접한 건물들이 드러납니다. 차 종류도 부족하고 일부모델들은 퀄리티가 매우 아쉽고요. 하지만 무료게임이고, 학생1인개발 게임이라는 요소를 반영하면 높게 평가할만 합니다. 화려한 차들만 있는게 아닌 상용차도 많고요. 분명 한계가 있는게임이지만 정말 잘만들었습니다.
