In the end it's apples and oranges. I like fast cars and fast bikes. Most of the cars that can "take" a bike in the 1/4 will get their ass handed to them up top because they've been geared to go fast in the 1/4. Easier to get traction with two big fat tires than just one so you can launch easier with no fear of flipping.
As far as a bike against a "real drag car" ... no way. Last time I went to the track (only a 1/8th) there were rail cars that were turning from middle 3s to low 4s.
The reason I like bikes better, and particularly the 1kRR, is because pound for pound you get so much more. My partner at work has a nicely built stang

that's fast but can't touch me in the 1/8 or 1/4. Can't touch me on top end either. Now let's talk twisties ... well, you get the drift. There are cars that can out handle, top end or 1/4 mile better than a stock liter bike but I haven't seen one that'll do 2 out of the 3.
