My neighbor updated me on her insurance claim from the accident earlier this year where 3 cars were written off, and another was damaged.

TL;DR: DON'T DRINK AND DRIVE, IT WILL COST YOU MORE THAN THE DRINK

I now have a rough total of how much the drunk driver is going to have to pay:

Write-off of 3 cars: $4000 + $3400 + $2000 = $9400
Repair of the 4th car: $2000
Hire Car (45 days @ $100 per day): $4500
Total Cost: $15900

So, that $10 drink is now going to cost him $16K.

Oh, and the costs only include my hire car. I know one of the other two drivers opted not to get a hire car, even though he was entitled to it. Not sure about the third.

Also, I don't know if the drunk driver's own car got written off, or got repaired, both of which also has costs, so add that to the $16K
