2012 Ford Focus, 155K miles, it is leaking a decent amount of coolant when my partner drives it to work but doesn’t even leak a drop if I drive it to work. The mileage is the same but I don’t sit in traffic. Could the extra heat from sitting in traffic be opening up a pinhole sized leak in the coolant line?
Edit: Thanks to a tip from the comments when the heat is turned on it leaks. I should be able to bypass that line pretty easy.

Are you sure it’s coolant? I know older focus had issues with the wiper liquid hose cracking.
I’m afraid that your partner has a coolant addiction and you need to get them checked into rehab.
On a serious note, perhaps sitting in traffic is causing the temp to increase and causing a leak. This would make me think perhaps the radiator fan isn’t working properly?
Does your partner blast the air conditioning?
Either way you should get a coolant system refresh and pressure test asap
Not a car expert, just a guy that learns how to do something when it needs to be done…
I don’t know how relevant the “why” is… you’ve got a leak, and the easiest first step is to inspect to see if you can figure out where the leak is originating from. If you can figure it out, then fix that. If not, the next easiest might be to just replace the coolant lines. If it’s still leaking after that, it could be either the radiator or a gasket.
Good luck!
