I've had to re-train my ears.
Like most drivers, unless I need to specifically know what speed I'm doing, I can judge it by the engine sound, ie I know that when the engine makes the sound it does at X rpm in 5th I know what speed I'm doing.
Now in my laguna, 3000rpm was 90mph, so I knew if the sound gets near that, I'm speeding.
In my new car, first thing I noticed was at 3000rpm the car's doing 110mph!
Time to ease off and just let the engine idle
70 is about 2000rpm.
