"getting drivers a street-level cab"
Now that's an interesting approach I hadn't heard of or considered previously.
Observation of other road users - and probably my own reactions, too, though I prefer low cars as a rule - seems to suggest that the higher the driver, the less considerate they seem to be of other road users. I wonder if it's just because from a higher vantage point, a lorry driver (or a large 4*4 driver) can see further ahead over other traffic and thinks less of the vehicle immediately in front of him?
Bringing the cab down to car level might increase the lorry driver's sense of vulnerability, which seems a logical way to persuade them to drive further than four feet from my bumper, as well as allowing them to look sideways...
Of course, if they feel vulnerable, they might not want to buy the lorries in the first place.
