(@ Jay3wheel) Kind of. Sort of. Not really.
Kinetic ENERGY is 1/2mv^2.
Your formula calculates out to twice the vehicle's kinetic energy, which is not the same as force. Force is mass times acceleration. Acceleration has units of distance^2 divided by time^2 (e.g. m2/s2).
Damages due to impact do relate to kinetic energy, but also how long it takes to dissipate that energy (impulse moment). The longer it takes, the less damage. The less energy, the less damage.
Dropping car mass does help (you arrived at a correct conclusion), but so does slowing down the dissipation of energy (crumple zones, phase change materials, airbags, and other energy dissipators.)
So Kronos's original question had a lot of merit. For a smaller vehicle, there's less area and volume to distribute the forces, and it's harder to engineer effective crush zones. Which is why EM has placed the wheels outboard and forward of the driver's knees. The bending and gnashing of suspension components will dissipate some of that energy, and also spin/bounce the car away at angles in offset crashes, which also reduces the impact's impulse moment.
EM also wisely specifies Electronic Stability Control which is proven most effective at avoiding collisions in the first place. About the only thing they could do better is to have automatic sensing of road conditions (ice, slick roads) and adjust tire pressures on-the-fly. But no such technology currently exists at affordable prices and reasonable weights.
