I hope self driving cars take the crown in the future. The more the F1 is regulated the more boring it get's (at least for me).
Since no driver is in danger they could make the cars faster and the race tracks more interesting. Maybe this will revive some of the race tracks that apparently are not on the F1 list anymore because they are to dangerous.
Or in the far future even high speed racing with weapons like in the games Rollcage, Wipeout, F-Zero and Extreme-G (of course with technology that is available...)
