Maybe I wanted to buy a slightly higher car and find the Kona more appealing than the i30. Who are you to police my taste? It’s still a car that’s not the gas guzzler you try to portray. You could also say the i30 is just a slightly bigger version than the i20 and now emmits more CO2. Where do you cross the line?
In my country I actually pay taxes according to engine size and emissions and guess what, I pay very little because it’s still on the lower end of the pollution scale. It’s a 3 cylinder for Christ’s sake! I don’t see you complain to sedan, offroad or sports car owners, and they pollute (and pay) way more than a small crossover. Or people that use their car everyday. I ride a small 125cc motorcycle everytime it is not raining. I bet I pollute a lot less than you do.
I dislike big SUV’s as much as you, but I find odd people trying to put them all in the same boat ignoring their body and engine size. People like what they like and have no need to justify themselves. If you’re worried about pollution talk numbers because that’s what really matters.
