Running ShowDebug console command during countdown in VehicleGame disables input

REGRESSION
No, occurs in 4.14.3

In VehicleGame, if the user runs a "showdebug" command (such as "showdebug animation" or *showdebug rawinput") while the starting countdown is going on, all input will be lost.

This doesn't occur if the user does it once the countdown is done.

So far I've only reproduced this issue with "showdebug" commands.

1. Launch VehicleGame in editor.
2. Play in viewport.
3. During the countdown, run the console command showdebug animation.

RESULT

User will not be able to control the vehicle.

WORKAROUND

Wait until the countdown is done before running any commands
