Teddy, I imagine in our league, elite tier, almost all of the cars (with attending managers) go into turn 1 of the first lap at PL5 no matter what tyres they're running. They're all very close together so chances are there would be carnage and half the cars would be out of the race. I'd rather not have that happen despite the realism.
BUT if you know the carnage could happen, you will think twice before pushing level 5, specially at the start of the race...
In your example even PL3 would lead to a crash in the first corner. So it's either going to risk it and hope no 4 cars are near enough or be happy loosing positions. Especially on hard. Then those calculateable rules give way for tactics like if the better car of the biggest competition is closing in from behind then putting PL 5, even though it cooks the tyres (making the car even slower). The other manager has then those really nice choices of going down with push and then being held up or wasting even more KERS to overtake or try to overtake with high push and crash both cars. Despite, even those slim chances using push to regularly overtake a slower car would be gone because the other one would just have to rise, or already running due to harder or worn tyres, his push as well to result in a crash.
What next, low push, which in reality is often more dangerous due to loss of concentration, after relaxing the mental tension of staying right on the edge especially later in a race, resulting in crashes as well? Those things just would just render the PL feature useless and with it any choice of what tyre to use.
