> If such trailers were rentable for a trip, BEVs could have much smaller and lighter batteries. Eg, my car could be substantially cheaper and lighter. hypothetically if this trailer solution existed, I still don't see people buying BEVs with smaller batteries. In general, most like the piece of mind of that range. Things happen - chargers break, power outage or you end up taking an unexpected trip or you spend some time at a friends home where you can't charge Given that the charger networks are growing at a decent clip and average charging speeds continue increase, not many people would want to bother going to U-Haul before and after a trip when you could just stop for a bit on the way, have some coffee and stretch your legs In short, it'd be such a niche product it would make little sense for auto manufactures in invest in it Rivan does have plans to let you add a battery pack for the bed of the truck. I hope that comes out and someday other brands do the same
