Re: Why not use appropriate technology?
60-70mph will likely get you killed on a US Interstate. Most of the Interstate network has a nominal speed limit higher than 60mph, a good portion is higher than 70mph, and most people are exceeding the limit anyway.
A couple of years back I was on a stretch of Interstate in Oklahoma which was prominently signed as "80 MPH, zero tolerance" or words to that effect. I was sticking to 80 and everyone else was blasting by me at 90 or higher.
Now that ordinary passenger cars are ridiculously overpowered, it's simply not safe to take a vehicle on US highways unless it's very large or can easily sustain at least 70mph. And I wouldn't be comfortable in a small car that couldn't get up to that speed by the end of the on-ramp, and for many parts of the network I'd want it to sustain 75mph at a minimum.
