It is necessary to put in order the system of commands for AI and the pressing of control keys of the vehicle, in accordance with the current state of the vehicle.
Under the spoiler - Keys and Commands, for different states of the vehicle. All the commands W \ S \ A \ D sound right for a stationary vehicle.
The reason is to change the sound commands for the driver AI and their sequence for the vehicle in motion:  - When the vehicle continuously moves forward / backward, commands to the left / right stop the vehicle after adjusting the movement left / right. This makes it necessary, after correcting the rotation, to repeat the command - "fast / slow forward"
 - When the vehicle continuously moves forward / backward, the back / forward commands stop the vehicle, but the AI command does not sound like "Stop", it sounds like backward / forward. It is distracting, it seems that you are giving a wrong command for AI.
