The biggest reason I went with dual motor is AWD. Maybe it is my inexperience with EVs but the single motor cybertruck is rear wheel drive. Living in Ohio we do get snow and ice. ICE rear wheel vehicles preform badly in snow and ice.
Having something AWD will eventually make me want to...
I currently do not own an EV, but I want to. For me I'd like to see all EVs do well. I looked at researched them all. I picked the dual motor Cybertruck based on needs and price point.
