Not really. The airbag is designed to deploy and stop you hitting the steering wheel. Most steering wheel injuries, which still occur with collapsible columns, are due to the driver sitting too close to the wheel so the bag doesn’t have time to deploy fully.

A malfunctioning airbag can be very dangerous and lead to law suits.

Seems obvious.

True. Highly relevant if you intend to buy a car with the airbag underneath the seat.

By the way, black suits you  ;D

I don't think a malfunctioning remote control will lead to a dangerous situation, injury or lawsuits, any injury will be due to either user error such as throwing it at something, or a battery malfunction. Wardrobe malfunction however can.

If the item doesn’t have sufficient safety warnings a lawsuit can result. Each remote control should have a label saying “do not throw this at anyone”. Similarly airbags apparently need a warning (for some people at least) saying “do not sit on this airbag).

However, this is drifting off topic so, to get back:
The reason airbag and seatbelt are there to prevent you hitting the steering column is that the column needs to be strong and not fail during the stress of driving. So, hitting it can still cause serious injury including broken wrists, internal injury etc.

PS black still suits you, singing less so  :D
