I always thought the drl in these Mirage's came on when you put them in gear(cvt), but I just went and checked and you're right.
This is on a cvt 2017'
- turn the key to run and drl stay off
-start car and drl come on
-with car running pull e-brake and drl lights stay on
-Start car with e-brake already on and drl lights stay off
-As soon as you release e-brake lights go back on and will not turn off with e-brake pulled.
So it seems the only way to not have drl on in a 17' cvt Mirage is to start the car with the e-brake pulled.
In a few years all new cars sold in Canada will be more idiot proof to stop oblivious people from driving around with their tail lights off.
