Skipping the integral coefficient in the PID controller.
Increase the number of seconds the vehicle should keep the target
speed from 5 to 20 to make this more important.
Increase the number of seconds the vehicle should be stopped from 2
to 5.
Decrease the extra punishment factor on exceeding target speed in
the twiddle algorithm from 10 to 2. There is now extra safety
margin implemented elsewhere which makes this less important.
Repeat the throttle tuning by
