Hello,
I've been playing these time trials lately and it's very annoying how you have to drive all the way back to the Time Trial start position to retry. I suggest you make it so the player respawns next to the icon after he aborted or completed the time trial, as soon as you bring him back to the 'real' world. I feel as if this is a suggestion that should be easy to implement and would improve QoL.
On a side note, I'd also suggest paying the amount per try instead of having to reset all cooldowns using the command, maybe by making a prompt that asks for 500$/1000$ on car entry.
