Should I feel horrible that I almost killed myself turning yesterday.. Metal pedal scraping the street is a very frightening sound when you're chugging through a turn.. I suppose super low turns are just not for us... but with sharp rights and small bike lanes turning with any speed becomes problematic without running into car lanes :(

if you're going fast enough to achieve a lean angle where you have to worry about pedal strike, you'd better not be turning into a bike lane without one or two car lanes open next to it. you'd be going too fast to see obstacles in the bike lane.

That's not true. Bikes with high BBs tend to corner faster/better, while bikes that have a lower BB tend to be more stable but not turn as well.
It's somewhat of a moot issue though, as all factory bikes in the US have to comply with saftey standards that prevent pedal strike. Unless you get a custom frame, there isn't a huge varation in BB height due to it.

With track geo, the bb is higher off the ground. Unless you go super sharp on a turn, it shouldn't be a problem.

Other road geo bikes, like my Peugeot UO8 for example, has a lower bb in comparison, and has a higher chance of pedal striking on a turn.

Even with that info, I haven't had a pedal strike. I try to be careful. Now toe overlap is another issue
