When playing is driving a wheeled vehicle, they can use use either keyboard or the mouse to steer. Without any mouse steering input, the wheel position auto-centres. This is reasonable. In some circumstances, rather than auto-centring, the steering input continues with the last received steering input (ie, continues to steer left or right to the steering limit with no user input). This is the opposite to the normal, desired behaviour.
In normal gameplay this is most obvious when driving, and opening the map. Expected behaviour is the steering would self-centre and vehicle will continue straight. However, if there was any turning input from either horizontal mouse movement or keyboard when the map opens, the vehicle will continue to receive the last steering input while the map is open. This results in the vehicle turning to a full steering lock turn very quickly.
Issue does not affect tracked vehicles, turrets or boats.
