Reducing tyre smoke when locking up?

I've just been watching a F1 crash compilation. In particular there was one where Grosjean span in the middle of the track. His car was concealed by the smoke generated by the tyres locking up and someone crashed into him. Smoke in general is, of course, very dangerous for following cars as it impedes visibility. Has any work been done to reduce the smoke generated?
 
I feel like smoke is unavoidable. It's just the way it is when heat is generated against the surface of tires and tarmac..... It's like asking if they should do something about gravity.....

Why? Rubber is just a vulcanised hydrocarbon (isoprene), isn't it? And hydrocarbons decompose to water and CO2, the latter of which is invisible.. So I wonder if vulcanising with something other than sulphur might be beneficial?
 
You say not to fixate on the Grosjean example but I don't really recall excess tyre smoke being an issue when you don't have drivers spinning the wheels up like that.

I've seen other incidents where locking up has generated significant smoke which has impacted drivers behind. Not necessarily causing crashes, but more than enough to impact visibility.
