Handling and braking mean more to me than acceleration in a car. So I'm going with the Clear Motion suspension system. I wonder if that's similar to the (eventually banned) active suspension that was in F1 in the early 90's? Even more than the Renault engine, that's the main technology that put Williams on top back in the day.
I also like the Elbee for what it represents for people who need such a vehicle. Independent mobility is great. If that also involves autonomous driving, that would be great... really life changing for a lot of people. The solar powered ventilation fans have been around for a good 20 years. My parents had one. Problem was, even though it provided ventilation, if it was 90 degrees outside, your car was still hot when you got in it... just not quite as hot as without ventilation. Maybe this one is more refined though.
