Lucky he's alive and even more lucky there was no one on the other side of the road... Hopes he really learns his lesson here.
This reminds me of when I learned my own lesson, I was playing around with a young guy in a brand new E92 M3 on a twisty road. The guy overtook me before a blind turn, was too fast and went straight into the barrier in the front. I saw his car flying and sparkles everywhere. The guy was alright but it got me thinking... What if there was someone coming on the other side of the road at this time ? All of them would be dead by now.
So even if you know your car and your limits, the guy you're racing with could be a complete idiot.
