Not yet, although I've tailed probably like three here in San Diego.
I raced one in my old S4 (w/ MTM chip (300+hp) and while he didnt spank me I had to work the S4 HARD to keep up. After 120 he start to pull even harder. I wouldnt mess with one on the open highway (they are not that fast in a tighter traffic situations, because they are boats) unless you're packing at least 300hp...even then you're still 100hp short on the top end, you'd get pulled up top.
We shouldnt have too much of a problem taking one off the line if you've got the usual ins and outs.
