>Re: amniotic: What kind of a van are you even driving?
Ah, sorry, I meant amniotic-like, hehe. I was reaching for a shorthand for a warm, throbbing, muffled sound environment. :)
At the time it was an old, under-powered Luton Transit, lots of noise and vibration in the cab. I haven't come that close to that unnerving experience of having to concentrate on keeping my eyes open since, but it concerned me enough to be wary of the phenomenon.
The Transit I drive now has electric windows - it might seem a small thing, but it allows me to safely open the near-side window, which brings cool air around my head more efficiently than opening the driver-side window (fluid dynamics, who'da though they'd be complex, eh?). Also, it's a quieter vehicle. In addition, the length of the 50 mph restriction are much shorter than they were a few years ago (but still there - what are they doing??)
Now, the other vans I drove - brand new 3 litre turbo Vitaras/Traffics, were like rocket ships when unladed. Possibly dangerous too, but they had a handy 'Eco' button that made the acceleration less insane, as well as a driver-adjustable speed-limiter. And air-conditioning.
