Some cyclists complain that motorists don’t give them enough room while passing. That’s less of a problem for recumbent bikes, but this gets me a lot more clearance:
There’s one section of very nice and totally gratuitous 6-lane highway (NY Route 55 near the NYS DOT Region 8 HQ; I think they’re just showing off) where drivers normally edge over to the left side of the right-hand lane where I’m riding. With a 20-lb propane tank lashed to my bike trailer, most folks have no trouble whatsoever with a double lane change into the far left lane…
The Smell of Molten Projects in the Morning 
I love my Bob, I really like the propane tank idea. I found another thing that works to keep cars at a distance (at least in CA) was to wear my HT on a chest harness. From the rear it screams Clint Eastwood…..
I’m sure the t-shirt helps: Honk if you’ve never seen a gun fired from a bicycle.
Of course, a recumbent rider’s t-shirt doesn’t count for much… [grin]
