You are putting the cart infront of the horse I am affraid. It is not
a matter of the teams allowing it. FIA sets the rules. The teams
do it or they are out. Period, no discussion.
And the grooves are on the tires to slow the cars down, causing the
driver to work harder. More or less as you thought.
Not really. Rumor has it that many teams have figured out to do illeagle
traction control. In any event the cars are not hugely slower than before
the grooves. That is also supposedly the main reason that Zanardi
claimed that he could not drive the F1 cars. Also Mclaren emerged
as the big power in F1 with the advent of the grooved tires. They
totally sucked in the few years before grooves. F1 gets grooves
and BOOM. It is like Senna and Prost again :-)
