Never seen this before! Was just trying to make a turn without rudder but by rolling: nice two-wheel driving until I hit the ground... First couldn't believe it, made a second try and, well see yourself... ;D
Ok, ok, sorry for that - will keep it in mind for next time (normally I had to resize the pics because of the file-size, but that time it worked, sorry)!
NP - on an oversized (pixel and/or fiel size) image, it's better to put in the basic link .... plus there's the " anticipation factor". And in this case, tender eyes that might otherwise have a conniption are spare the jolt of seeing a nice car turned over...
