[4vxc]

There was a well known drag racer killed about 10 years ago in the states after his top fuel car hit a concrete pole in the braking area .
For what ever reason the blame was put on the high speed of the car and lack of braking area, so straight away they stopped all top fuel and funny cars from running 1/4 mile and shortened it to 1000ft.
There are plenty of ways to reduce the speed of the cars rather than have different classes running different track lengths.
Funny thing is that the IHRA used a recent 335mph run in Australian as a example of the excessive speeds but thats exactly the speed they have got back to in the usa running 1000ft.
