My mother told me that traveling to Portland, OR in the early sixties, my father was going 80 mph on I-84. Now the maximum speed limit on that highway is 70 mph and is 65 between The Dalles and Portland. And up until 1995 when it was repealed, the national maximum speed limit was 65 mph, 55 in urban areas. And before 1986, it was 55 mph everywhere. And yes, now there are places were the speed limit is 75 or even 80 mph, but they are rare. And, again, that's how fast my parents were going in the early '60s.
I was driving on I-84 a few weeks ago and on some straightaways I could see for miles and couldn't see another car. I had the cruise control set at 75 mph but it felt as if 80 or even 85 would have been perfectly safe.
Why aren't we traveling faster? Why aren't we moving at supersonic speeds through the air? Why don't we have bullet trains like in Japan?
The Concorde consumed a lot more fuel than a regular jet. Which is why it cost so much to fly on it.
The US is too big geographically and population density too low to make bullet trains practical outside of the East Coast population centers and maybe parts of Southern California (San Diego to LA).
Some companies are working on a "hyperloop" that can travel at 700 mph which is faster than commercial airplanes. But like high-speed rail, it's expensive and probably not practical in the low-population density areas of the country.
I don't know what the answer is. We need a breakthrough in speed. I don't know where it's going to come from. Maybe autonomous cars will go 100 mph while we sit inside and look at our phones. I don't know. That sounds almost as bad as flying on an airplane.
Why do you think we're not going any faster than in 1960? What do you think might help that? Let me know in the comments below.
