Strangely, I prefer the strawberry shake
I was thinking, if he had on his lap (assuming he used the drive through) say, a Big Tastey - we know it would have been even more unwise to race. What with all that extra salad and mustardy-mayo sauce they put in - it would have been an interior wrecking opportunity of grand proportions.
Edit: The thinking/racing man's sandwich of choice is the humble cheese-burger - Surely?
It's lightweight, no frills and your done in two bites - ready to take on the Saxo.
There's more. If he'd also got a coke on the go, rather than a shake, the basic force of acceleration acting on the soft drink recepticle and lid would annihilate his interior, once again, with sugary wetness. Now a shake on the other hand with its extra viscosity can sustain a decent and tidy acceleration.
So to conclude, not only is it a matter of road safety (he passed the test) it's a matter of fastfood physics. I say the guy did well.
I once watched my kebab go for a burton, in my old MK3 round a roundabout.
