After Tesla's announcement Tuesday that its new Model S P100D (when equipped with the optional Ludicrous Speed mode) is the fastest-accelerating car you can buy, it sure seems like everyone wants to talk about racing down a drag strip.

Luckily, our pal Jason Fenske with Engineering Explained is here to, well, explain to us just how fast normal cars can (theoretically) get.

There's still some room for improvement, but, as Jason points out, we're getting to the point of diminishing returns. 

In his informative style, Jason breaks the fastest possible 0-60 mph time down for us in this roughly 7-minute video. How many times could you have accelerated and braked 0-60-0 in 7 minutes? You can do the math on that one.

And let's remember that the Model S P100D on Ludicrous Mode (with Luda himself in the driver's seat, perhaps) isn't the fastest-accelerating car you've ever been able to buy. Ponying up more than $100,000 for a Model S is, however, admittedly a lot easier than finding a Porsche 918 Spyder. Tesla says it will build about 200 P100Ds per week, which means it'll take less than a month and a half for the California carmaker to have more cars on the road capable of zipping to highway speeds in 2.5 seconds than Porsche. 

That's a little scary, if you ask us—but let's not knock the notion that going fast is seriously fun.
