There is a big difference between "street legal" and "street driven". Most of the quick cars listed here might have a license plate but they sure as hell are not driven on the street on a regular basis or for any distance, let alone hundreds of miles at highway speed. E.g., Z-Gad recently had to get his chassis certified and drove a couple of hundred miles to get that done. Got back just in time to swap tires, throw in the race gas and drive ot the track to do his license runs and clicked off a 9.1 @ 147+ trying to avoid 150mph because the car still does not have a parachute. Now, that is a street driven car, not to mention I drove it home 400 miles from SEZ 2 years ago!
Unless a car has a timeslip to back up its claim or reputation, you cannot compare it. There is a ton of information that can be gotten from a timeslip beyond just the ET. You can still tell a lot about a car's power and potential even if the ET is not stellar because the car is not setup for drag racing or the driver has no 1/4-mile driving experience.
