F1 drivers call for more checks after drain cover incidents

Triple world champion Max Verstappen said more checks were needed after Formula One's pre-season testing in Bahrain was halted for the second day in a row on Friday by a dislodged drain cover.

The two separate incidents revived memories of an incident that caused considerable and costly damage to Carlos Sainz's Ferrari at last November's inaugural Las Vegas Grand Prix.

Verstappen, chasing a fourth successive championship this season, feared the current high-downforce cars were making such incidents more likely with the suction of their aerodynamics.

"Maybe these kind of things can be checked a bit more. We know that this is a potential problem with these cars and when you go to certain tracks you know where the drain covers are.

"So I guess before you start driving at the weekend to double-check that everything is solid is a must for the upcoming tracks, (so) that we don't have another situation where cars get destroyed.

"Especially with a budget cap in place as well it's not nice when these things happen."

Sainz's Ferrari's survival cell, engine, energy store and control electronics were all damaged beyond repair in the Las Vegas incident, with the team still waiting on an insurance claim.

"It's a serious issue because it can have big consequences and we have to look into it for the future, for it to not happen again," said Ferrari's Charles Leclerc on Friday.

"Yesterday we were quite lucky that it
