The problem with making an extremely small, lightweight car with a hardtop is you get something like the Exige, and try getting in an out of one of those with any sort of dignity.
On my way back from shipping out the Gungnir, I almost got the opportunity to replace my car tonight at someone else's expense when a big Ford truck signaled to change lanes with me directly next to them and instantly started moving over from inside to outside lane. I mashed the brakes and moved as close to the curb as I thought I could and I have no idea how we didn't trade paint. If I hadn't noticed him changing lanes I would likely have ended up face first into some road hugging trees at 50mph. Arkansas plate.. always bad drivers. Guess companies putting in those blind spot warning systems will help those people. I was clearly visible (my roof was above his window line) and was almost matched with his front axle so I had to clear the entire length of my car to avoid impact.
That's another reason why I'm not particularly interested in 2,000lb toys. If I get T-boned in my A6 at an intersection, most likely nbd. Probably some bruises and a stiff neck. An MR-2 in the same situation? They'd be scraping you out of the car with a shovel.
There's a counter argument to that though that myself and UncleErik used to agree on. The smaller sports car keeps you more focused and engaged (alert). Plus it reacts much quicker to impending idiocy and can get you out of trouble. In an MR-S or other MR, you don't hang out next to trucks, you just zip around them because the car makes you want to. Seizing initiative on the road is a huge factor for safety. Hanging out next to morons at the same speed in a clusterfuck while people are zoning out or texting is a recipe for disaster.But yes, be dummer than the car or the road and you will pay the price.
