The fact that the measure was not "shellacked" is a testament to how much the people of San Francisco care about public transit, depend on it, and want it to be better.
Officials in the Bay Area think by using inexpensive plastic and paint (and sometimes gently curving, concrete curbs) they're designing streets to keep everybody safe, motorists included. But what they're really doing is transferring the consequences of reckless driving from the perpetrators to everyone else. These past few weeks we've seen the tragic results.
Dangerous motorist behaviors, such as speeding, crosswalk incursions, and going the wrong way on a one-way street, are tolerated by law enforcement and a judicial system that basically never suspends or revokes the license of even the most egregious offenders.
