That's a very good point Bindi, any ICE and hybrid era will be on the way out come 2020 in most countries in favour of all electric. Should f1 be looking even more towards electric motors or completely pivot and bring on hydrogen fuel? I do think there is a conflict that its hard to justify spending so much on development if it all comes to nothing in the real world. These are corporations at the end of the day that ultimately compete for research (which can happen elsewhere) or prestige. I wonder if AWD is on the table. It sounds unlikely and none of the teams seem to have mentioned it.
