The survey was conducted as part of the Roulons électrique campaign.
That campaign reached people who are already aware of electrification because they already own or use an EV, so high numbers were to be expected. The satisfaction rate or no-return rate is actually 99%, which is really impressive.
Once again, this shows that testing an EV is enough to convince people not to go back to a gas-powered car. Saving money can really make a difference.
