I thought I'd just add a bit of perspective. One thing I do whenever I get a new car is to take it out and do a high speed brake test and maximal cornering test, just so I know what level of capability the car has. Because braking is highly dependent on the front tires, and those are narrow and an all-season compound that isn't designed for maximum grip, the stopping ability is about where I thought it was. I looked it up in the only instrumented test I could find of my car, Car and Driver doing the ED test in 2013, and saw it had a 70-0 braking distance of 190 feet, which was actually the worst of the six budget electric cars they tested:
2014 Chevy Spark EV vs. Fiat 500E, Ford Focus Electric, Honda Fit EV, Nissan Leaf, Smart Fortwo ED ? Comparison Test ? Car and Driver
The 453 was a couple of feet better at 188 feet:
2017 Smart Fortwo Cabriolet Automatic Test | Review | Car and Driver
As a comparison, a modern sports car can do a 70-0 stop in about 130 feet, and some even less. That's a 60 foot or five car-length difference in stopping ability.
The main takeaway is that modern automobile brakes and tires are really good as they are on a Smart car, but even so, don't even remotely get close to tailgating a higher end sports car on a freeway because the braking level on those cars is breathtakingly excellent.
