The NGDV is dorky as hell. But I bet they're very effective for drivers.

I've got an old cabover passenger van, visibility for me is pretty good, but if you were next to it on a bike, you wouldn't be able to see over the hood cause there isn't one.

It's also pretty dorky, but it's got essentially a porsche engine, which makes it a rear engined mid-life crisis sports car. I have to run it at red line for 30+ seconds to get up to freeway speed...
