Formula One needs to be taken from the engineers and given back to the drivers, according to former Renault team boss Flavio Briatore.
"We need to lower the costs but also the technology because right now the drivers are clicking a thousand buttons to the right and to the left," said the Italian, who cannot return to F1 until 2013 due to the 'crashgate' scandal.
"The engineers have taken control," Briatore told Onda Cero radio, "with regulations that are difficult to interpret.
"We saw what happened (at Silverstone), with rules on a Friday and different ones on a Monday. The spectators aren't interested in that, they just want to see the drivers fight.
"We need to return to a more normal F1, as in the days of Senna, Prost and Mansell, and Alonso at the beginning. In the last five or six years it has become way too technical," he insisted.
