Unsolved Deleting Vehicles in Scenario

I am able to delete a vehicle "vehicle3" in a scenario using TorqueScript.eval(command) in the function onRaceStart. The problem starts when the scenario starts to run an onUpdate() from the statistics.lua. It is trying to get speed data on the vehicle that I deleted. How can I remove the vehicle3 from onUpdate() call?

Here is the log info:

Can anyone help me out with this?

 

I am still trying to figure this out. Also if I delete the ai vehicle the player camera does not work.

 

So I found out that if you press "R" on the keyboard to reload the scenario then this error disappears and I get the player camera back. Is there a way to reload a scenario from my lua script?
