Decreases your tendency to flip over. I'm astonished by all the dashcam videos out there showing collisions, usually the first thing an ice car does is flip over. Not EVs though.
That's more a factor of weight distribution rather than weight itself.
EVs carry their weight lower to the ground. SUVs and pickup trucks are more top heavy. Passenger cars have a higher probability to rollover, but not that much greater than an EV.
Ice cars have a much higher rollover risk compared to EVs. All the data supports that along with physics. Absolutely weight distribution. Compare the heavy battery in an EV vs the heavy motor that's up a bit higher in an ice car. Pretty much any hit over around 20mph to the front quarter panel of an ice car, truck, or SUV will flip it over.
