Much of the problem isn't snowbirds. It's the low rate of prosecution for vehicular manslaughter. Southern states seems especially tolerant of driver irresponsibility, perhaps because the victim is perceived as 'an outsider' -- i.e. not someone cluelessly driving a giant SUV.

"Walking may be hazardous to your health. In Florida, the risk of fatality on foot is significantly higher than in any other state.
Nine of the 20 deadliest U.S. cities for pedestrians are in Florida, with Orlando ranked as least safe and the Miami-Fort Lauderdale-West Palm Beach metropolis ranked No. 14 in the 2019 “Dangerous By Design” report from Smart Growth America and the National Complete Streets Coalition."
If you like walking or biking, don't move to Florida.
If you're white, perhaps. As a matter of public policy, this form of institutional racism is a way more effective way of producing a desired outcome: coming down hard on people of color while letting white people off easy. The incidence of fatal escalation of routine traffic stops is way higher with people of color.
