Fire. The anti-rollover devices make it difficult to safely remove
gasoline from a tank before removal. That leads to spills, or not
bothering to try. So there tends to be gasoline vapors floating
around. The guy in the next bay fires up a grinder, sends a spark at
the tank, and Whooosh! You've got a nice fire.
Talk to an insurance company that writes garage keeper's insurance, and
ask how many of their fire claims are for fires caused by this, and
you'll learn it's a substantial number.
