Former F1 racer Olivier Panis has hit out at the new Drag Reduction System and labelled the device as dangerous following the opening three races of the 2011 system.

The system enables drivers to open a flap on the rear wing of their car in a designated zone on the circuit if they are within a second of the car in front, which in turn boosts top speed and should make it easier to overtake.

DRS played a key part in an exciting Chinese Grand Prix but Panis said he felt the system was dangerous due to the added work it gives a driver on the steering wheel and that F1 chiefs should look more at a circuit design to find a solution to a lack of overtaking.

"I don't like it," the Frenchman told GPUpdate. "Seriously, if you want to have some overtaking like in China, you need to do it with the circuit; if you put a hairpin before a long straight, for sure you will have overtaking. But all these kinds of things, I don't like them at all.

"Really, there are too many things for the driver to be doing on the steering wheel now. Compared with what they did before, I think it's more dangerous and I don't feel good about this philosophy. First he has to change gear...and also if one time the system doesn't work it's going to be pretty dangerous, particularly in a high-speed corner.

"I don't really understand who decides these things and if the guy was smoking something before he did. Really, I don't think F1 needs these types of new things. I hear a lot of drivers complaining about it and I agree with them. I really don't like it and I think it's too dangerous in relation to the show it gives us."
