There's always a bigger fish. Remember that when you're bragging about how fast your Ecoboost Mustang is. The guy you're talking to might have a Mach 1 in his garage. And if it just so happens that you're the Mach 1 owner, be sure that you may bump into someone who drives a Shelby GT500. But it doesn't end there, there are scarier cars still.
For most people, a 760 horsepower Shelby GT500 is already too much to handle. But some people will straight up drive one and reckon they need more power already. And thanks to modern technology, you can pretty much upgrade any vehicle that runs on an internal combustion engine and bring it up to your desired level of performance.
