# The player's car drives itself after a scripted driver was stopped

## Symptoms

In the next race the player's car accelerates or turns with no input. Positions read from memory
show it moving from the countdown.

## Cause

The driver script holds keys with `xdotool keydown` and releases them with `keyup` on its next
step. `timeout` stops it with SIGTERM between the two, so the keys stay down in the X server
(*observed*: `xdotool keyup Up Down Left Right` stopped the car).

## What to do

Release every key the driver can hold in a `finally` block, and turn SIGTERM into a normal exit
(`signal.signal(signal.SIGTERM, lambda *_: sys.exit(0))`). After any killed run, send the keyups
by hand before the next race. GameFrame's `winput` releases every key that its `down` step
holds when it ends, and has a `release` step for a run that was killed.
