I see that the Stewards were busy during the Test Day on Sunday - over 40 Decisions - a few for exceeding the 60 km/hr limit in the pit lane (usually caused by the driver forgetting or being slow to activate the speed limiter or not being in 1st gear); fines issued - and many for multiple violations of track limits; stop/gos of 5 minutes being given.
This won't get better as the week progresses. Almost certainly, the winner of the 24 will be a car that has not picked up any penalty certainly during the race, but probably during the week.
