Have you actually driven a smart? I have, and it has no problem keeping up with traffic, or accelerating to highway speed. If you want acceleration in a 2 seater, go buy a S2000. The smart works for what it was designed for, and economical and fun commuter car. It also happens to work really well on our large interstates. Go test drive one at your local dealer before writing it off as slow to accelerate. I think you will be pleasantly surprised, unless you drive a C6 Corvette everyday.
