A place to discuss the characteristics of the cars in Formula One, both current as well as historical. Laptimes, driver worshipping and team chatter do not belong here.
F1 currently has so many engine maps that it makes the current V6 engine a kitten when it really is a monster.
Kimi proved for second race in a row that the engine has so much torque (within the fuel limit) that it can spin the wheels at the rev limiter or 4th. All the makings for a monster series which requires some serious foot work to keep the car moving.
Yet with these innumerable maps it is impossible to see these in action.
Should the engine maps also be restricted like gear box forcing the engineers to use the highest torque setting possible and letting the driver do all the work from fuel economy to drivablity?

The problem for the drivers is not the torque it self, give them twice the torque and a dry track and you will see that there is no issue for the drivers. When you see the drivers lose control these days, it is because of the ERS systems that can make the torque unpredictable and erratic, that is causing the cars to snap.
knabbel is right, its the KERS that brings the instant and perhaps 'undriveable' torque to the equation. That's why the power delivery is so important to get right and make the car driveable and predictable in all circumstances to inspire driver confidence. I foresee Kimi losing confidence in the Ferrari and having a tough rest of the season.
Teams are only allowed two proper maps for torque demand, and they're heavily restricted. Everything else relates to fuel-mix, ERS, etc.
5.5.3 The accelerator pedal shaping map in the ECU may only be linked to the type of the tyres fitted to the car : one map for use with dry-weather tyres and one map for use with intermediate or wet-weather tyres.
5.5.4 At any given engine speed the driver torque demand map must be monotonically increasing for an increase in accelerator pedal position.
5.5.5 At any given accelerator pedal position and above 4,000rpm, the driver torque demand map must not have a gradient of less than – (minus) 0.045Nm/rpm.
I agree with the others about the nature of Raikkonen's spins. It's likely an ERS-related issue, and my guess is that it stems from partial-throttle harvesting.

Running the ICE at a higher fuel flow produces more overall power, which in turn allows the MGU-K and MGU-H to recover more energy to recharge the battery. It may sound counterproductive to use more fuel to become more efficient but just a small percentage more fuel leads to greater car efficiency through improved driveability. Overloading is particularly useful at circuits were there are few corners and therefore chances to recover energy.
Done right, that can emulate a rudimentary form of traction control. Done wrong...

During the Spanish Grand Prix weekend, Sebastian Vettel and Kimi Raikkonen were losing half a second to their Mercedes rivals in the tight third sector, where traction is key.
"If you look at the third sector, it's traction sector," said Arrivabene.
"If we are not able to solve the problem it can be worse not in Monaco - because in Monaco you have special settings - but in Canada.
"I don't want to go to Canada with the same problem of traction otherwise it will be a nightmare."
Ferrari has been struggling with this since last season. Note the "stuttered" throttle response just after the start and again after turn-4.
