<human>: Not just for cars, but for other runners/cyclists too. 

Sorry for rant, but here it goes:
I was out for a run and crossed a cyclist on the way. I'm always very attentive so I saw his face, what he was wearing, etc. About a mile later I turn around and see he is  behind me. I think this is strange since I had cross him a mile back, so I slow down and try to let him pass. He seems reluctant so I cross the street and slow down A LOT. He eventually has to go on ahead but once he has done that he stops by a hidden area and looks back to see [I think] see where I was. I slowed down again so he keeps on going and I take a turn. I think everything is fine when about a mile later he appears out of nowhere and seems to be looking for me. I was next to a golf course, and If I kept on going I would have been in a very isolated area so...I called a friend for help and got picked up. Later on the police scolded me for not calling them first and immediately. I positioned myself between some golfers and while waiting to be picked up, he rode back one more time and seemed to be looking for me. It was very scary, but I was glad that I was aware of my surroundings and that if he did have bad intentions I didn't get to find out about them.

Can you give me the gist of the text in a nutshell?
<bot>: always be aware of your surroundings. Don't just look out for cars. Even during daylight some creepy people may have bad intentions!
