<human>: Can you condense the text into three sentences or less?

Yesterday, actually. I was driving down the highway in the middle lane when I notice that someone is going the exact same speed in the passing lane next to me.  I look over and see two cute blonde girls trying to get my attention.  The passenger used a marker to write a phone number on the window.  It took a little while since the marker seemed to be dying.  While this was happening, I notice that the traffic is piling up behind our two car road block.  I punched in the number and sent a text just as they were taking an exit and I continued ahead.  Apparently, I got the number wrong.  
Now I'm kicking myself for not taking the time to follow them or at least being more diligent about getting the numbers right.  
I'm hoping they see the missed connection post I put up on Craigslist (does anyone actually check those?).
<bot>: Cute girls tried to give me their phone number on the highway.  I fucked up the number and now I'll never see them again.
