Sounds appealing, and it's an idea I've considered too, but it's still a bike. Nowadays there are a lot of rocks on Angeles Crest - that's a more serious issue on a bike. And then there's the gear you should ride with, and the fishbowl you have to wear on your head. Also, it's not silent and I believe I read that their range and power is reduced dramatically in hilly terrain.
New cars have made dramatic advancements with respect to noise. Tire quality and brand make a huge difference. But with Angeles Crest, the premature resurfacing they did last year took it from being a whisper quiet road to something much less so. I'd suggest a carefully selected convertible for an open driving experience that does not require leather pants...unless you're into that kind of thing.
