I have an Acura RDX with remote start on the keyfob and it is very difficult to accidentally do. You have to first lock the car from the fob, get back a response saying it’s indeed locked then hold the remote start button for several seconds before it will start. Any other inputs in between those two actions cancels out the remote start sequence. It also shuts off after a few minutes if you don’t get in and actually “start” the car just in case you did manage to accidentally trigger it.
