That is Barbara Streisand.

When the interstates were designed, they were designed to be safe at 110 mph in automobiles that were available in 1950.

Today, we have automobiles that are much improved with safety equipment.

The real problem is that it is way to easy to get and retain a drivers license in the U.S.

Reflexes have almost nothing to do with it. Judgement and training is a lot more important!

And how many automobiles driven in the US are safe at 110 mph? Very few. For example, most US cars don't have high performance tires rated for those speeds. Throw in the fact that many cars are poorly maintained and these speeds become dangerous, irrespective of the qualitites of the driver.

By the way, you are wrong about reflexes not playing a role. They play a big role and there are definite limits to what a person is capable of on a public road.
