How is it the "world's fastest car"? "The world's fastes car" isn't quite the same as "the fastest from 0 - 60". It's a one trick pony for publicity reasons.
Since 99% of driving is done at speeds a Prius can achieve the maximum speed listed really have 0 significance for most of humanity. None. Motor trend and other top end speed oriented press folks have a lot of work to do to change the perception of what is good and useful, they still speak lovingly of the sound of pollution and waste exhaust...really in today's world they have not progressed their journalistic writing beyond an analysis done in the 1930's.
Why do I want a car to make a sound? Never ever got that. I've driven everything from tractors, to illegal street hot rods, to small planes, to forest harvesting forwarding skidders. Every group of users has some % that enjoys hearing exhaust...so maybe I am odd. For me, I'd like to hear the wind and birds and not much more. Reason i like sailing, mountain biking, etc.
So a vehicle such as a laferrari is designed to meet very specific check boxes (high price, high top end, production limited just like prints in an art gallery, barely street legal, etc) they are never going to be driven at top speeds, the cost is a selling point geared to an an unholy income distribution skew, and it is deliberately production curtailed to make it collectable.
Better to measure fastest cars with 50,000 vehicles on the road. You'd drop all the useless chaff right off that list and be left with a Porsche 911 and Tesla. Both great cars, both exciting. If I want chaff I'd put NASCAR frames on there, they have more vehicles than some of those "production" cars. By dropping the chaff you'd force motor trend to discuss driving rather than salivating on some ridiculous checklist that has nothing to do with driving.
I summary, if you want fast go to bonneville (really-that is a blast). If you want to discuss exciting driving for the normal joe...than yeah Tesla is amazing, head knocking back gravity defying acceleration with perfect traction control that no other vehicle can touch. Yeah, it's pretty f'ing awesome.
