I would like to see the continuation of research and development on multiple ways for people who ride to ride safely--not just feel safer, but be safe, as well. Not everyone who rides a bike is going to be comfortable with vehicular cycling, and I'd like alternative ways for them to be able to ride. I think that can be done in time, and I'd like to see that work continue.
I did see the Roosevelt/UW bike lane as a driver and it scared the daylights out of me. It dumps out very sharply with little notice or signage just before the U bridge, where a third lane merges in from the left. I too would not ride it as a cyclist yet. But that doesn't mean I want all those bike path alternatives wiped out in general principle. I want them improved. I like greenways too--bike routes through quieter streets that can get you through parts of the city.
I think multiple approaches to safe riding are really worth continuing to look at as long as they are done well and carefully. The world each of us is comfortable in, riding-wise, isn't necessarily the same as other people's, and I'd like those other riders to also have safe ways to ride in the city.
