Fernando Alonso says cockpit protection is now imperative for Formula 1 - and argued "we don't need heroes in the sport right now".
Debate among drivers over whether F1 could introduce a head protection device onto cars has been reignited at the Russian GP after Red Bull gave a first public test to their 'aeroscreen' concept.
The partial canopy has split opinion, but Alonso, one of the grid's most experienced figures, believes there should be no argument if a concept proves it can reduce injuries to drivers.
"I think it is a must for safety. We don't need heroes in the sport right now," he told Sky Sports F1.
"We saw many incidents and many occasions in the last couple of years. Probably all the deaths we had in Formula 1 and junior categories came from head injuries.
"So I think we don't want anyone getting hurt in the future. If there is a solution in place, and it seems it can be a solution, let's introduce it."
The McLaren driver suggested the aeroscreen looked better than the halo that Ferrari previously tested, but hopes there are more ideas in the pipeline before F1's governing body settles on one design.
"We need to trust the FIA on the decision. They have all the information about which one is better, comfortable, safe," he said.
"There are many factors we can't control, we just look from the outside, but the Red Bull solution probably looks a little bit better from an aesthetic point of view. The FIA will decide the best one - and hopefully there are more options coming."
