I have used my US visa card on multiple French motor ways in 2016 and 2017, without any issues.
I don't think they care; it works fine with the magnetic strip.
The same is true in parking garages and any shops I tried - supermarkets, bakeries, restaurants, etc.

Personal experience: It depends. I was able to use my Canadian card on some highway tolls (A7 Lyon-Marseille) but not others (A8 Orange-Nice)
The safest bet is to choose a lane with booth attendants that can accept cash in case the card is refused.
Most merchants will be fine with any card, but I've also had automated gas pumps refuse my card.
