Not true. Their safety ratings are very respectable. Don't be fooled by the small size - they incorporate a steel safety cage that uses the other car's crumple zones. Keep in mind that the majority of people never have a collision. For those that do, it's almost always a slow speed one where a Smart Car has excellent protection. If you are one of the unlucky people who get hit by falling Oak trees and speeding fuel tankers, nothing is really going to help.
Our Smart is very reasonable to insure. I note that the OP has quoted on fairly extensive coverage. Raising the deductibles will help bring the cost down.
They might get decent ratings but I still wouldn't trust the thing. The only time I've ever been in a car in an accident I was in the back seat, sitting at a red light, and we got rear ended by a drunk driver going over 40 mph. Pushed us 250 feet through the intersection. If we were in a little smart car, we probably would have all been dead. But we were in a newish Camry (08-09ish) and we all walked away without a scratch.
They also just look like they wouldn't be very stable at highway speeds. A few months ago I was driving home on the highway at about 1am and all of a sudden a deer appeared about 30 feet in front of me right off my right bumper. Luckily my car handles amazing, is low to the ground, and has symmetrical AWD so I swerved right around the thing and missed it by what seemed to be about 5 feet. Having driven a couple of vehicles that are box-shaped like that smart car, I'd be willing to bet if you tried to do that in one of those it would end up tipping and rolling over.
I just personally wouldn't trust the thing and they don't seem very practical either.

Buyers choosing the smallest cars for low price and high gas mileage could be endangering themselves and their passengers, says a major auto-safety researcher.
In new crash tests, the Insurance Institute for Highway Safety rammed three automakers' smallest cars into their midsize models. Although the small cars had passed other IIHS tests, they flunked in collisions with larger but still-fuel-efficient sedans. "The safety trade-offs are clear," IIHS President Adrian Lund says. "There are healthier ways to save gas."
IIHS, funded by auto insurers, usually crashes cars into stationary barriers at 40 miles per hour. This time, it was car into car, each going 40 mph.
....
• Fit vs. Accord. The Fit crash-test dummy registered severe leg injuries. The dummy's head also slapped through the air bag and whacked the steering wheel.
• Toyota Yaris vs. Camry. Yaris nearly lost a door. Its driver's seat tipped forward. The dummy's head hammered into the steering wheel.
• Daimler Smart vs. Mercedes-Benz C-Class sedan. IIHS says the Smart "went airborne and turned around 450 degrees … a dramatic indication of the Smart's poor performance, but not the only one." Much of the interior was shoved into the crash dummy "from head to feet."
They just aren't worth it when you can get an Impreza or Civic for the same price, get the same gas mileage, have way more passenger and storage space, and be way safer.
Also, I know my posts in this thread have been pumping up the Subaru's a bit, but since the OP was originally about insurance costs, it's worth noting that the symmetrical AWD in all Subaru's (except the new BRZ) is actually considered a safety feature by insurance companies and you actually get a small discount because of it.
