To minimize injuries.
Cars have improved in many ways. The advent of seat belts, safety glass, anti-lock brakes, air bags, power steering and power brakes have all improved cars.
Airbags prevent excessive forward movement in a front-end crash, therefore, reducing injuries.
Only on some of the high end market cars do you get double and even triple glazing. Most comon vehicles do not have double glazing but instead they the safety glass.
Yes, cars have lots of safety features but motorcycles don't.
olden day cars have no safety belts
A number of safety feautres are in cars now to try and prevent accidents. Airbags, stop a person's face from breaking into the steering wheel. Seatbelts, stop a person from coming out of a seat. During an accident, you may be forced through the windscreen if you have not a seatbelt on. Crumplezones, help so that if you crash into, lets say a lamppost, your car will crumple, but will slow down to stop you from being injured.
The 1950 Ford cars did not have many safety features, like we do today, in place. The cars and trucks did have safety belts.
Ford heard of a development in England by a company called Triplex of a laminated glass that had two pieces of glass with a plastic liner in between them. He got a patent licence on that product to introduce them, and that became the safety glass that then went around all the windows on cars.
Cars should have doors and seat belts for safety features. Other safety features include: airbags, safety locks and anti-lock brakes.
