You need to do 100mph to pass? Really? Hope you don't get clocked at that speed you'll be posting from jail
My sentiments exactly...... if you need to exceed 92MPH to pass another vehicle, may you should consider giving yourself more distance before executing a pass, not more speed.
Assuming the person that you are passing is doing less than 80, you would be passing the person @ over 12MPH. @ 12MPH, it should take about 5 seconds to pass.
About 10 years ago, in my '98 Silverado 5.7, I came up on a Cavalier doing ~65 on a long, straight, level 2 lane road in the middle of a clear, sunny day. Son and I saw headlights of an oncoming truck waaaaay off in the distance, and both agreed there was ample space and time, so I began my pass at 70. Our truck went to 98, when the limiter kicked in; meanwhile, that oncoming truck got real close real fast. Yeah, we made the pass in less than 5 seconds, but that didn't mean squat in light of the fact the oncoming vehicle was probably doing the average speed of 95 that all people do on that road (SR 198; Coalinga - Hanford). But we could not gauge that when the truck was so far away at the onset of the maneuver. See why I would like the extra fudge factor? It's not about me; it's about the speed of oncoming vehicles and the ability to accurately assess it from a great distance.
Sounds like this is a road to tell your son not to pass on
Most roads in the CA Central/Northern Valley are like that; those agricultural people drive when they get out there!
