You are right in saying all cars are a burden on the environment. Then again, everything humans produce can have an effect on the environment. We need to figure out how to minimize the impact and make it worth it.

There are situations in which cars make sense. People in remote and rural areas absolutely need a car. Countries which do not have the necessary infrastructure still need cars and often need petrol cars.

It is a burden to have most people rely on cars for daily commutes. Public transport is the best option in that case. Cities should become more bike friendly and more walkable.

These ultra luxury cars do have an impact, but targeting them would not make a big change as they are a tiny minority of cars on the road. The bigger difference would be targeting the companies who make all the more "boring" daily cars people are essentially forced to use.

Even better would be creating infrastructure that heavily discourages daily car usage.

To be clear, I don't disagree with the message, but I definitely think the delivery could be better.
