Thanks everyone for the support and advice.
I researched straightening forks last night, learned a few things. yes shops are reluctant to do it though some seem to specialize in that. More common in motorcycle shops, some of which have special tools for this job. This post from "miamijim' was particularly helpful:
"2. Legs. The legs can be bent to either the side or back or a combination of both. If your front wheel looks 'tilted' to either side when looking at it from the front chances are the legs are bent to the side. Simple fix...grab legs and pull. If your wheel looks 'twisted' or appears to out of alignment with the crown (crown and stem are aligned but wheel is off center) one of the legs is bent back. Easy fix....grab leg and pull."
Most discussions were about steel frames. Apparently aluminum is easier to bend but easier to weaken after bending, especially if there is a visible or palpable 'crease' in the metal. I learned that a bike can be suspended upside down by strings attached to the wheels, and if it hangs with the wheels in line the frame and forks are likely straight. I learned that a dowel inserted straight into the hole in the bottom of the fork crown will run straight down between the fork arms and serve as a rough gauge of true-ness. Several recommend using a length of steel pipe as a lever.
So. Today I took another good look at the thing. No creases. I sat down and put the wounded beast in my best submission hold, gripped one fork arm and put some pressure on it in the direction of true. Nothing. I increased the pressure, felt nothing. I thought about how a couple of years ago the city repaved the now six-lane street where my accident occurred, how they put in NO bike lane and how there was NO convenient parallel low traffic route and that there are tons of bikes on the sidewalk along that street. How they approved a mini-strip mall at the busy, dangerous intersection on that street where my accident occurred, how I have no choice but to ride on the sidewalk against traffic there, how difficult it is for drivers to get into and out of that place.
I got really angry. I pulled really hard. I felt the thing move! Eventually I got things somewhat straight. Here is the result:
I think there may be a bit of lean to the rider's left remaining; however I took her for a test ride and, other than some looseness in the handlepost, everything seems OK. I did the recommended "hands off" test (OK not completely hands off as I have never been able to do that safely with small wheels) and did not detect any pull. Rode to the LBS where the mechanic who would not touch it was somewhat impressed. I'll probably still get a new fork from Thor just to keep him in business. I'll revisit by fork tweak after a few more days of riding and perhaps adjust. How's it look in the photos?
Here's my total loss so far: One wheel destroyed, rim gone, spokes and dyno hub maybe salvageable with a rebuild. Fork damaged. Front light/reflector gone. Plastic horizontal water bottle cage broken. Handlepost loosened.
The driver was apologetic and gave me a lift home (ain't folders great?). He left me with his card, and offered to pay for repairs. Technically the accident was his fault, he should have yielded to traffic on the sidewalk he was crossing. In Florida it is legal to bike in either direction on the sidewalk.
However I place the blame for this accident squarely on the traffic planners who were apparently oblivious to bike traffic when they expanded this street. I avoid riding on the sidewalk, especially against traffic. But there was no feasible safe way to avoid it on this trip. The driver was occupied with oncoming traffic and not looking to his right where I came from. I am normally very, very conscious of this driveway as I know drivers are distracted there. However on this occasion I suppose I was distracted by dodging the dude blocking the sidewalk by waving one of those huge signs advertising one of the businesses in the strip mall. As soon as I ducked past this guy, the SUV appeared in front of me and I could not brake in time.
I am undecided how much of the repair I will ask the driver to pay. He does not seem like a rich guy.
Thanks again to everyone for the help.
