EVs generally aren't small ... a Ford Lightning is the same size as a regular F150 of the same body style (because it's the same bodyshell). A Ford Mach-e is not small. A Hyundai Ioniq 5 has a 3 metre wheelbase. The Bolt and Kona are the smallest long-range EVs, and they're the same size as a recent VW Golf (which is fine with me). Granted, we haven't seen EVs in the heavy-duty pickup class yet. The EV Cadillac Escalade is coming ... one of my last projects involved a weld cell for an inner body component for that. It's sure to be enormous.
I'm not aware of a difference in collision involvement. All of these EVs are modern vehicles with modern crash structures and safety features. The center of gravity tends to be low, which is good for roll-over mitigation (less likely to happen) and that's good, because roll-overs are among the most dangerous types of crashes. Insurance rates for my non-Tesla might perhaps be a proxy for collision involvement, and they aren't anything special, neither good nor bad. (Teslas are infamously expensive to repair)
Fast acceleration can be a double edged sword ... it can get someone out of trouble, or it can get someone into trouble. Most modern vehicles are fast enough to do either. Being modern vehicles, they've all got traction and stability control. Bolt is motor-RPM-limited to 150 km/h, and most EVs have artificial top-speed limiters in the interest of (a) battery, inverter, and drive unit thermal management and (b) helping preserve at least some sensible amount of range in the event of the driver being stupid. For that matter, a good many modern vehicles of all types have artificial top-speed limiters - tire ratings being one factor.
