Another "victim story".
I managed to pull in an open slot on a dual left turn, onto our "Stoney Trail", highway bypass loop. (no jokes on the Stoney thing please.) It was next to an Audi R-8. I chased him all the way down the on ramp, and strangely managed to hold 20ft off his rear bumper, up to the legal merge speed.
He was of course watching me in his rear view mirror, and holding me to whatever distance he chose. Meanwhile the noisy Ford eco-boost pickup that was behind him at the lights, faded into the distance of both of our rear view mirrors. All legal speed limit stuff... no laws broken. I have to say though, that an R-8 shifting at nice high RPM, just about broke my heart for the old days.
