Houston has some of the worst (and most hostile) drivers around. Many will try to come as close to a bike as they can, just to send a message. But, for some reason, most are much more careful when they see an UNUSUAL bike. When I tow a trailer, cars move six feet to the left, instead of their customary six inches.
I think the Sun qualifies as "unusual". It is the sort of bike that folks slow down to look at, notice, and give wide clearance to. Richard Ballantine commuted to work in an ultra-low racing 'bent that had him laying almost flat on his back. He said New York drivers gave him a great deal of clearance, and seemed to notice him more than when he was on a regular bike.
The Worksman is a great bike for use on a factory floor by a fit 25 year old man. It would be about the worst bike in the world for broken pavement, potholes, and hilly roads. Which is why NOBODY has ever seen a Worksman on a public road (not counting the ice cream vendors and food deliverymen).
