I have three cars that I consider dangerous, MGA Bugeye Sprite and an Austin Seven. I have no problem with my son in any of them, but would never put him in the back of a motorcycle or ElioBTW Elio will be offering( of course an option)a sun roof and a moonroof, the structural members have been so designed, perhaps that will alleviate your concerns- if it really is a deal breaker, then perhaps your concerns might best be addressed with another type of transportation- 50 years on bikes - risk vs reward.
More people have and will die crashing on motorcycles then I ever could imagine sitting in the rear seat of an "&" with the driver incapacitated -seizure/heart attack -just don't try the passenger door to exit
