Somehow this got me thinking of “50 shades of how I met your mother”, which surprisingly nobody else seems to have already done. 
Damn! If you plan on calling him back, let me know first so I can invest in Kinko’s, anticipating the rush of prospective lotharios printing off bulk copies of their digits to distribute to everyone they pass on the street! 
Reminds me of the guys who say they ask every girl in the bar if they wanna fuck. Sure, they might get slapped 99 times, but so long as the 100th says yes…
I’d say wait for someone driving something better than a Cobalt.
Seriously, I’m male and have been out of the game for 3 decades, but I’d think a woman pretty desperate or indiscriminate to respond to such a drive-by approach. And I’m trying to think of any guys I knew who would have had the nerve to do that. I’d really think someone would try to at least strike up a brief conversation, or ask if he could buy you a water/juice after your run.
Finally, I’d be remiss if I didn’t make the obligatory request for photos - both sweaty and cleaned up! 
I need to rethink my original plan to try this approach as an experiment. I don’t have a car (or even a driver’s license). And I’m not in great shape. So after I’ve given my number to a jogger, I don’t have a way to escape in a hurry. If I run away, they’ll probably catch me.
If anyone can help me out with this little issue, I’d appreciate it.
I thought you were going to say you expected reams of “girl missing” flyers to have to be printed.
Since I didn’t see anyone else comment on this:
If he likes athletic women or is into fitness, you might have looked your best to him.
At worst you waste a little bit of time on a creep.
At best you just found your husband and the father of your future children.
Assuming you want to get married and have children.
I say go for it.
At least he had the balls to approach you.
As far as having the number ready, maybe he’s seen you before and came prepared in case he saw you again.
Ok, I’m going to preface this by acknowleging that I’m a older, slightly bitter woman.
To me this kind of pick-up is creepy. He knows nothing whatsoever about you except that you’re female, that you run, and that he finds you attractive. You might be dumb as a post or be the Original Bitch on Wheels (not that I think you are) but that doesn’t matter because, hey, baby, you’ve got nice legs and a great ass, so here’s my number. This strikes me as a man who is looking for something other than good conversation. If that’s okay with you – hell, maybe you want the same thing – then text him and see where it goes.
Personally, I’d throw his number away.
Yeah, I told you I was bitter.
hey - he could have slammed on the brakes , parked quickly then started running/chasing after you to give you his number.
Lazy SOB ‘drives up’ to give it to you? what are you, a fast food drive thru?
“hey baby, we’ll be back to pick you up later”
How is he supposed to find out what kind of object she is as dumb as unless someone approached someone first? How do you think people get to know people they’ve not met before?
Yeah, so what? It’s a date at most, not a marriage proposal. The purpose would be to start figuring out if she’s dumb as a post or the original bitch on wheels or actually compatible.
I’d say text him. If it were me, I’d probably text from my google voice number instead of my regular number, but assuming any initial attraction were there, I’d be curious enough to text.
Its obvious. The Cobalt driver gave his number and this website.
At least we know it wasn’t M.Bigfoot. He doesn’t have a car or drivers license.
I bet a dollar the OP never returns. But she has received great replies here.
This may make a [del]very good[/del] film from the '90s starring Sandra Bullock.
Thus is the shit-hole that constitutes modern dating.
Guy expresses interest in a girl and offers his number.
Girl runs to her computer to ask anonymous strangers what to do.
Fuck modern life.
… Only after getting advice contrary to her initial instincts. What better tiebreaker than a bunch of disinterested randoms? (Well, there are probably some, but still.)
Shit. I just hope we won’t be on the news in the near future.
“Shortly before the woman went missing, she received advice to contact the suspect from a well-known internet message board…”
Oh, well. Could be worse. At least we haven’t talked any cyberbullied teenagers into killing themselves lately. As least as far as I know. I haven’t checked the Pit for a while.
Amen.
How much balls does it take to do this? At worst he risked her looking confused and/or scared. If you approach a woman at a bar, she might laugh or tell you to fuck off if you are coming on too strong. But I would guess most women would be fairly polite even if they think a guy is a creep if he’s giving them their number from his car, because he might be the type of guy that would follow them home, or maybe even just hit them with his car out of a rage. Women have been injured or killed after rejecting guys, and a car can be a big death machine. It seems like a fairly chickenshit but also possibly threatening way to try to hit on women.
In this case, apparently the guy didn’t seem like a creep, and Marylnshephards didn’t feel unsafe, and I don’t blame her if she does decide to text him. But I really really hope that other guys don’t see this as a good way to find dates.
By meeting people in normal places and talking to them? Chevy Cobalt guy could go to a bar, or a club, or any number of parties, or Meetup events, or volunteer, or join a church, or intermural league, or any number or other things. And that doesn’t include all the specific dating routes he could take, like any number of dating sites he could join, or speed dating events or singles events he could go to.
And yes, Chevy Cobalt probably wouldn’t specifically have met Marylnshephards through any of these other routes. But he knows absolutely nothing about her, other than what she looks like and that she goes jogging, so really, it shouldn’t be that great of a loss for him.
Pretty sure they started doing that a long time ago. It’s called a business card.
wait, was it a printed card or just a number written on a piece of paper? because I definitely get the number written on paper thing
Yeah, the creepy part for me is the implied leering from his car and bugging a woman who is simply out for a run. If he had handed her his number at a store, bar, or even a beach I wouldn’t be so suspicious. To me, cruising around in your Chevy Cobalt looking for hot and sweaty joggers raises a red flag.
