They used to have lotteries for grid positions. They didn't keep it up. I wonder why.
One of the key things in any
sport should be that it is a meritocracy. If you do the best job, you win. There are various ways to make a grid more likely to be mixed up, but none of them should ever say that the fastest legal driver should ever start anywhere but from pole.
There is no appeal to a sport that may decide a championship by a narrow margin because of a lottery*. For example, imagine a championship of 5 races where these are the grids:
You can argue with my conclusions here, but one suspects that Valtteri Bottas' performance in this theoretical five race championship may underestimate the job he/Williams were doing. You'd also get the feeling that Daniel Ricciardo would do very well out of this, too.
Yes, there'd be more overtaking. Hamilton would get past a lot of people in race 1. There'd even be a pass for the lead (likely Vettel passing Grosjean). But would these be battles? Could we cope with Hamilton having to pass a McLaren, two Toro Rossos, two Saubers, Perez, Kvyat, Haryanto and both Renaults to actually join the Mercedes/Ferrari fight, through no fault of his own? How could Daniil Kvyat hope to show Red Bull bosses that he should keep his job if he twice started last while his team-mate started twice from pole, equally unmeritoriously. Not great. (In actual fact, the sheer number of Mercedes/Ferrari battles makes that list pretty much the best case scenario.)
Asking for lottery systems doesn't show understanding of what a sport is, and why it is important to preserve equal chances. It wouldn't improve racing, it would falsify the results and it would make that champions' trophy feel a whole lot more hollow than when drivers had to work for it.

Penalty shoot-outs, despite what has been said by various numpties, are not a lottery. In football in particular, but elsewhere when they are used, they are a test of skill under pressure. The difference between someone who is not able to apply their skills in this way (Gareth Southgate), not able to handle the pressure (Frank Lampard, Steven Gerrard (2006)) or is confident and skilled (Antonin Panenka) is evident from their records. So, no, that's not an example.
