The accident is horrible news, I have to agree with the sentiment that it's unrealistic to expect the city to be able to keep up financially with covering all old tracks, or cover those that might be needed in the future. I used to ride in Philadelphia, which has used and unused trolley tracks everywhere. And even some of the tracks that were covered in asphalt have begun to break through again, so that's not always the solution. It just becomes an unfortunate fact of life, especially in economically disadvantaged neighborhoods/districts.
I once got caught in a Philly trolley track, and went over the bars hard. Bruised ribs. But the only thing do is just get back on the bike when you feel better and be more careful. Sucks, but that's the card we're dealt. It's hard enough to advocate for painted bike lanes, let alone major reconstruction of large swaths of city streets.
