Ex pizza-delivery driver checking in. I made about $15/hr (incl tips) delivering for dominos in 2007. I drove a $2000 truck and didn't much care about coverage on it. It was the best summer job I ever had.
If you have nothing, it's highly unlikely you're going to get sued. People who sue always look for the party with the most money, and try to shift the blame to them.
That's what I made around year 2000. Though I delivered 'Better Pizza, with Better Ingredients'!
Gas was $1/gallon and we got 70¢ per delivery. I asked a friend about 2008 or so, when gas had gotten up to almost $5/gallon briefly (part of the cause of the Great Recession, I'd imagine), and he said they were still getting 70¢ per run. That sucks.
Also, only 1/10 orders used credit cards, so nobody paid taxes on tips - all cash. By 2008, I'm guessing it was 1/3 using credit, and now, with apps, it's probably 9/10 using cards.
But yeah, it was a sweet gig if you weren't the social / beautiful type to be a successful waiter or waitress / bartender. It paid more and was way more fun than making $6-$8 / hour at McDonalds or Target.
What crushed us was when dominos implemented the "delivery fee". As drivers we only got ~1/4 of the ~$2 fee per run, but customers began treating it as though it was a tip.
