Describe alternatives you've considered

Testing

Tested while driving a vehicle at 32 kph and saving and then loading.

Before: Offset is centered on player on reload. Stopping of the vehicle leaves the view offset in the wrong position. Press of the : key resets the view offset to the correct position on the player.

After: Offset correctly accounts for the vehicle speed on reload. On stopping the vehicle the offset is adjusted to the player. Press of : key has no effect because the offset has been handled correctly and is already centered on the player.
