So I'm doing 45 in a 30 mph 2-lane rural road in the W124 and I spot the cop approaching from the opposing lane...yep, I'm busted!
I don't even wait for the police cruiser to U-turn and start pursuit. I just turned into the available cross street and wait, engine off, window rolled down with my arm outside, license and insurance card in hand.
Not sure if the officer was astonished or impressed by my refreshing gesture of honesty, but he politely informed me that "this particular strech of road was plagued with frequent accidents", and to "pay close attention to my speed from now on".
End of story. He let me go on my way...
