Why? Because tow truck companies don't want to get sued by the incredibly wealthy. But, they'll tow your Nissan in a second.
Also, if a rich guy doesn't want to pay a parking ticket? He has lawyers, or even a law firm, to deal with that. What's a 100k legal fees to someone who makes 50 million a year? Around a days pay.
Imagine having a bunch of lawyers that can handle your legal troubles, and win, for one day of your pay. You wouldn't even blink, would you? Nope.
And the poor? Some can't even pay the ticket, end up owing more in fines for unpaid tickets, get bench warrants for arrest for failure to pay tickets, fines, and if they miss a court date? Instant jail time.
Same original offense... far different outcomes.
