I (27F) was followed today

Sharing this partly to get it off my chest but also to warn anyone who frequently walks in the area!

I was followed around 5PM today while walking along 11th St (from Folsom to Mission). As I was crossing Howard, I noticed a man on the opposite side of the street, leaning against his car which was facing me (an old model, low-set sedan colored navy blue / dark greenish - didn’t catch the make). He stood up straight when he saw me crossing / walking towards him and I was uncomfortable so I took a left onto Howard instead of continuing straight. I then saw his car pull up to my left, and he parked a little in front of me and started opening his door. I took the first right and started running. I then saw him driving down that new street, towards me, so it’s clear he quickly spun the block when he couldn’t stop me on Howard. Luckily there were two other women on the street so I walked with them. His insistence on following me with his car makes me think his intention was to grab me and put me in it (if he just wanted to talk to me, he could’ve called for me or walked towards me like other cat-callers, instead of getting in his car each time…). Needless to say I’ll start taking busier streets - I never considered 11th to be “quiet” and definitely didn’t think 5PM would be a “bad” time to be walking alone, but this city is clearly full of surprises…

Edited to fix street name (initially said Minna when, after checking my map, it was actually Howard).
