Re: Now ask me why ...
newer cars are much safer than the older models
Possibly, although (a) newer cars are a lot heavier and go a lot faster so they have significantly more kinetic energy when moving and (b) safer for the vehicle occupants, perhaps, but not necessarily for pedestrians, cyclists, dogs, etc.
There's also the problem of risk compensation, where humans tend to convert safety enhancements into performance enhancements. Knowing you have excellent brakes allows you to drive faster and brake later, compared to a car with known-rubbish brakes. All very well until something unexpected happens, and every single "accident" on the roads is unexpected.
