My wife bless her really tries to be a good pillio and really is fantastic nowadays. Back when she first got on with me, after shed not been pillion for about 15 years, she nearly did everything right!!
What she forgot though left me permanently mentally traumatized. Coming to a red light, the ass in the work truck in front of me slows normally to 10 mph then without warning slams on his brakes for no reason well before the line. We are on my '02 955i 'tona, thankfully because it has brakes like hitting a brick wall when you really need them. I grab pretty hard and then it happens...130lb of soft lady com slamming Intl my back, as a result, I of course slide forward.... right into the tank resulting in two bruised "eggs" shall we say.
She now holds onto the tank and braces for stops. Couple weeks ago I even caught her back there hanging off nearly as far as I was while hauling ass on some corners (like 95mph in a 35, must have made her feel the need to help me turn Lol).
