Ok, nice read. Now I'm thinking that you being 42 yrs old and lovin these speeds without saying you've tracked cars is weird. I mean, I would expect you to pursue your cravings on a track and hit some great times, right?
Now, I have the advantage of using the autobahn quite often and my X clocked 240kph (148mph), but there was no dangerous overtaking, because I wasn't the fastest on the road
Your girlfriend's driving was a bit uncalled for not to mention posting it on youtube.
I sold my X5 and got an M5 which is a speed demon. I, however have not hit it's top speed because I love how she handles at "lower" speeds and play around with traction. I guess, what I'm trying to say is that wreckless driving at high speeds is dangerous. PLEASE BE CAREFUL.
