Funny thing about that GIF....McQueen is actually in Reverse and is backing up in that scene, not going forward! So a little creative editing! And yep...Bullitt wasn't a Traction Lock.... open rear!
Another intertesting thing to note, that engine stand in Mikey's garage picture was photo shopped in. Under that crude cut- in is the Ohio clan with one hand on the hood and another holding their drinks!! I'm telling ya...... it's true!!
Cheers
