I would think it would be fairly hard to accidentally fully deploy the kickstand at highway speeds. With the spring retention and the wind resistance, you would have to hit it fairly hard...every once in a while I have to tighten my highway pegs on the crash bars as the wind forces them down. If you somehow managed to accidentally bump it, most likely your foot would slip off and the kickstand would slap back into place. Meanwhile, your foot would end up eating asphalt. I've never paid attention to just when the motor shuts off, does it shut off only at full extension of the kickstand, or somewhere between retraction and extension? Now full deployment at speed of course might be catastrophic...footboards would be a good solution, but with 14EEEs you might be cramped for space. I have footboards with heel/toe shifters and size 13 feet. There is barely enough space for my boots to clear both gear levers, additionally, the heel lever is very easy to trip by accident...when I shift up in gear, all I have to do is barely bump it. But the system works great and has me completely spoiled, I will never go without boards and heel/toe shifters again! Of course if you only had the toe shifters with boards, I would think you should have plenty of space.
