I think I'm the only person who has ever been back there and it was only like once or twice to clean. Like others, my biggest problem was getting back out.
I've actually had a decent amount of success. One woman I waved at while passing decided to follow me until she could get next to me to roll down her window (it was tinted) to wave back. I've noticed the Mach-E drivers either are oblivious to other Mustangs or don't wave back.
