> Driving is high risk activity that can lead to severe head injuries. It is even easier to keep a helmet with your car than with your bike. The cost to risk profile here is extremely similar but the resultant behavior is quite different. Just FTR, don't wear a helmet while driving a car. It will massively increase the strain on your spine in the case of a crash and your airbags are not built with helmets in mind. Additionally, car helmets are usually of the full-size kind and reduce your field of vision quite a bit. There's a reason helmets are not recommended for normal driving.
