I don’t believe that F1 is too easy, but I do believe that circuits are much too forgiving. Cars are much more drivable but no way they are easy to drive.
In the old days there were manual gearboxes and massive turbo lag. Driving up to 90% of the limit would be crazy hard, pushing to 100% and beyond would be supernatural. A car today would be fairly easy to get to 99% but the last 1% requires immense skill. The thing is, that last 1% is hard to see without a stopwatch because it involves epic fine precision invisible to the naked eye but seen in the telemetry.
Personally, I would rather see drivers visibly wrestling a massively powerful wiggling sliding beast.
Modern cars are definitely no smoother than cars of 15 years ago, but onboard cameras today are much smoother. Compare the suspension travel on a modern car compared to something from decades ago (before aero).
Top cars are generally more balanced anyway. The RB6 is quite beautifully balanced. When Martin Brundle drove Schumacher’s championship winning Ferrari F1-2000, he was amazed by its stability. Watch an onboard lap of an HRT. Struggles at every corner.
Drivers of today are much fitter than they have ever been and pull more G’s than ever before. I don’t believe that Fangio or Piquet (at their prime) could last a full race distance in Bahrain or Malaysia (though I doubt Vettel or Hamilton could handle Fangio or Piquet’s cars).
I agree that circuits are much too forgiving. Too many crucial corners are surrounded by parking lot runoff. The bus stop at Spa should have resulted in more carnage on the first lap this year instead of all of the front runner’s driving happily across the smooth tarmac runoff. I don’t believe circuits should be deadly, because it’s nice that a driver can show up for the next race, but I do believe circuits should be punishing. Suzuka is nice that a mistake will send you far off into a gravel trap and Monaco will rip off at least two corners of your suspension. Being punishing without being deadly is possible, just look at the wall of champions in Montreal. Tarmac runoff areas need to at least shred tires to death to justify their existence.
