MinggI think I might do this. Hahaha it would be a shit show but still the best way of doing things at this point hahaha
They might stall but once they get moving you have highway ahead. If you need a rest try and make this happen during a time of day/area where it isn't likely to be stupidly congest.
If traffic is getting wild and they freak out can just tell them to pull over. If it's coming to stop just have them push in the clutch, put it in neutral for them and have em coast to the side and swap.
Actually almost got smashed by an asshat in a porsche while swapping with my friend doing that on a road trip. Bad traffic and some douche decided to go balls out down the should and barely stopped, then beeped at us because we were blocking him. I decided to take my sweet time on the shoulder and he eventually merged back in with traffic.
Also a bunch of people mentioned cruise control. Def good to use if you have it. Just remember to turn that shit off if you're getting really tired. The last thing you want is to chance falling asleep and have the car still on the gas trying to maintain 75/80 into a tree or guard rail.
