@Silverchild79,
this whole "slowing down" concept is bullshit.
maybe in general it will work.
but me, in my car, i don't even go into 6th gear driving normally until 80mph. below 80 in 6th there's 0 power because i'm too low in the rpm band, and thus, i need like 3/4 throttle to even accelerate to 80mph whereas in 5th gear, 60-80 requires 10% throttle at best.
I get FAR better milaege in 6th gear at 80-90 than i do in 5th gear at 50-60.
politicians need to learn more about cars and transmission gear ratios, aerodynamics, and so on.
