That would be good for the environment if it would replace larger cars, but seems to end up bad for it (globally. Locally, going electric likely is a plus), as it mostly replaces scooters for healthy teenage drivers, which should be replaced by human-powered bicycles.
The environmental footprint is not that clear-cut here, because humans are generally bad at turning food into energy, so cycling has a footprint of anywhere between 22g/km (vegan diet) to ~80g/km(average US diet rich in beef) of CO2 per kilometer.
Meanwhile a kilometer of driving this vehicle in France has a footprint of ~7g.
The battery's manufacturing footprint sits at around 450kg of CO2 - and this is something that has to be "paid off", but it's entirely possible within the car's lifecycle.
Basically unless you're vegan, it's likely more environmentally friendly in France to drive this.
Walking is less energy efficient per km than cycling, so by that logic, we should spend our lives in electric wheel chairs. I don’t want us to go there.
Luckily, it may not be true that this is more environmentally friendly than cycling. I would think this 485 kg car uses more road space and causes more wear and tear on roads than a 25 kg bicycle. That must count for something.
You also have to take the health benefits of cycling/the effect of more car driving on obesity into account.
