Wanna know why you shouldn't go that fast? Even at 5 mph, collisions are severe enough to cause thousands of dollars in repairs:
The impact forces are HUGE at higher speeds. Yes, the car may sacrifice itself to dissipate some of the energy to protect you, but there's only so much it can do. At 110+ mph, you are asking for a lifetime of paraplegia or death.
You're right of course, but an accident at 65 will kill you just the same as one at 110. Past about maybe 50 mph, collisions just stop being surviveable with current restraint systems. That's not to say we can't do better, but most drivers wouldn't tolerate the systems used in race cars.
Most collisions involve smaller speed differentials anyway. Considering that most Interstate traffic these days moves at 80 to 90 driving at 110 only represents a 25 mph speed difference. Certainly survivable, and slow enough that you can hopefully react to avoid an accident all together if someone swerves in your lane. The biggest problem on Interstates are the drivers who insist on going right at the speed limit, or even under it. How they do this without falling asleep is beyond me but they are a bigger hazard than experienced drivers doing 110 or 120. Another big problem are kids just getting their license who really can't handle high speeds but drive fast anyway just to show off. Despite my brother's penchant for speed, he definitely won't try doing 110 on a crowded road where everyone else is doing 65. That's suicide, plain and simple.
What we really need are to set reasonable speed limits based on a road's curves and the capabilities of modern cars. Many cars today, especially foreign ones, are perfectly capable of cruising safely and economically at 110 or more. I would like to see speed limits set around there, and perhaps up to 125 on very lightly traveled, straight roads. Also minimum speeds that are maybe 20 mph under the speed limit to keep the half-assed drivers who think 60 mph is moving off the highways. Besides the obvious increase in traffic flow efficiency, we might finally start to see proper lane discipline in this country, and remove the plague of SUVs from the picture. They just aren't stable or economical at 100 mph so they might not even be allowed on most Interstates once the minimum speed was raised to 90 mph or more. As their utility decreases, so will their attractiveness to the general public.
