Florida may be about to approve a new law that could potentially ‘harm’ its supercar scene.
At least indirectly.
For now, Florida has laws in place that determine whether a car is too loud in a ‘scientific’ way.
But with this new law, critics argue that things may get worse.

How does the current Florida law work?
Current Florida law sets specific limits regarding how loud a car is allowed to be.
There are limits for the city, and then limits for the highways.
We can talk about whether those limits make sense and are fair until the cows come home, but the fact of the matter is that they’re objective.
If you’re within the limit, you’re legal; if you aren’t, you get a fine.
So far so logical, but the problem is that law enforcement agencies have struggled to enforce decibel limits, and roadside testing is difficult and expensive.
For this reason, Florida lawmakers have already approved a new bill which, if signed by the governor, will be the new law.
This is why some people are already criticizing the upcoming law
House Bill 543 moves away from scientific measurements (in decibels) in favor of a more subjective ‘plainly audible’ standard.
The bill specifically targets drivers when they are intentionally revving their cars or unreasonably accelerating to create noise.
And that’s the problem.
Because critics argue that without a hard decibel limit, the law is open to interpretation.
There is no scientific way to assess what words like ‘intentionally’ and ‘unreasonable’ mean.
Florida is one of the most supercar-friendly states in the US, and some supercars are just naturally very loud.
Even modern supercars aren’t ‘safe’.
They use electronically controlled valves that make them artificially quieter or louder, but a V12 is a V12.
You can’t really expect it to be quiet.
On top of that, people are arguing that this, along with newer (and stricter) speeding laws, may harm Florida’s ‘supercar-friendly’ reputation.
