Former F1 driver Mark Webber believes the standard towards the back of the Formula One field has "never been weaker" and that the cars are well below the level they should be at.
Webber retired from F1 at the end of 2013 and has been racing in the World Endurance Championship for Porsche ever since. He believes he got out of F1 the right time, but can't help but think the current grid is not as talented as it used to be.
"These guys are on a phenomenal level but the depth has never been weaker," Webber told BBC 5Live. "If you go from the top 10 back, there are a lot of pay drivers. This is not good, we need to get the calibre that we have at the front of the grid.
"We need more depth and the cars to be faster, noisier, whatever. Put them on a level where they are further away from other categories. The cars I'm driving now are very similar on lap time, GP2, the category below F1, is very similar on lap time and it's not right."
Asked if it was now easier to win a championship, Webber added: "It's still tricky. The physical components are the lowest it's ever been, but it's not the drivers fault. It's like a rugby union tackle but 30% softer. You don't need the physical component [anymore], when you had the G-force, the need to hold your breath in the corner, when those were at their peak in the mid-2000s you just have to look at the lap times.
"All the racing lap records are from that era and we are miles away. That comes from the physical side of the sport and the drivers would like to be challenged a bit more too.
"It's a bit like being an F-18 fighter pilot but flying for British Airways. They're within their comfort zone, pacing races. It's frustrating.
"F1 should be the pinnacle. It should be by far the fastest through the corners, physical on the drivers and things where the drivers are the gladiators again.
"The car still needs to be something the fans have never seen anything like before. There's so many categories which are close to them now."
