Smelling other vehicle's exhaust in fresh air mode?

I'm smelling other people's exhaust in fresh air mode. not so in recirculate but recirculate automatically returns to fresh in all positions beyond 2/3 forward vent 1/3 floor. I'd like to force recirculate in all modes. i understand the rationale behind Chevy's decision to do this. i just entirely disagree with the notion that i am incapable of cracking the windows when the cabin needs new/fresh air. and i do not like breathing noxious fumes because Chevy insists on it. I'm open to any/all possible solutions. Thank you and be well.
