Ok, more excellent questions!
Our vehicle has not been crash tested, from the structure however, we know it is well built and I would suggest it is at least as safe as a g-wiz, I don't know what g-wiz have done recently to improve the safety of their cars to be honest.
On from this, our product along with the others currently in this market are not cars! They are quadracycles, lower speed EV's mainly for town and city use. we are not pretending it is anything else, and our user information will reflect this fact and whilst I absolutely agree that it may not be as safe as a car in some crash situations, but then neither are motorcycles, mopeds, or cycles for that matter. In the matter of safety in the event of an impact, I would suggest it sits below a car but well above a motorcycle.
I don't think there is an arguament for government intervention on safety grounds, or else where does one stop? Should we make it illegal to ride cycles, mopeds & motorcycles and force everyone to buy a car because it's sometimes safer? Can't build a kit car because a production car is safer? or drive an older car? You see my point
Regarding liability on failure of parts leading to injury, we aim to ensure this doesn't happen in normal use, this is why we have chosen the supplier we have with ISO certification. Ultimately, I don't know the answer to the liability question, but we will be able to confirm this prior to point of sale but I expect it will lie with the manufacturer of the specific part that fails, in the event this causes a dangerous situation other than that which can be caused by "normal" failure of a component as happens often in all makes of vehicle.
