show me a real car doing a huge, billowing burnout (thus, generating the heat in the tires required to accomplish said burnout) while lifting the front 5 feet in the air for almost 100 feet on a public road like in the movie.
these weren't little tire scratches or chirps, but a huge NHRA style burnout with the front tires in the air.
you can very easily launch and lose traction then lift the front that high when the tires finally hook. that's not what happened in the movie.
The thing is, you're not losing friction in a burnout. If you lost friction, all you'd be doing is spinning the wheels--like what happens on an icy road when you start out too quickly. What friction you've got is the dynamic friction between the tire and the tarmac, and that's what smokes up the tire, etc.
In any burnout, you get a torque on the axle as a result of that friction force. Normally, all it's going to do is unweight the front a little. What I'm suggesting is that, if you had the right weight distribution and tire characteristics, you could potentially get enough torque about the axle to lift the front clear. Once you've done that, there's nothing to hold the vehicle back, and the reaction starts driving it forward--and that gets you the "100 feet down the road" part.
All that being said, I'll easily agree that it's a really unlikely situation: you'd need the perfect combination of tire compound, pavement composition, weighting, engine characteristics, and probably a dozen or more other factors to make it work. But it's not impossible.
