I don't think it is a good solution at all - regular consumers buy cars that are type approved and certified as cars by various regulatory bodies, and they should expect that normal parking spaces should accommodate their car because that's what they own. If you made a "car" that was heavier than 3500kg it wouldn't be type approved as a car anymore, it would be classed as a truck and you'd need to have a C/C1 licence to drive it and you wouldn't(shouldn't) expect to be able to park it everywhere. Why isn't the same rule applied to dimensions? Normal car that can be driven on a B class licence should weigh less than 3500kg AND it should be smaller than whatever the problematic dimensions are. That's not to say that cars like the i7 shouldn't exist - just that they shouldn't be classed the same as a Toyota Aigo.
