Electric cars are as zero-carbon as the cost-equivalent space of a freshly paved asphalt concrete highway or parking space. If not more than that due to the more special materials required to make them.
Also note that, due to much heavier weight of electric cars, asphalt concrete surfaces will be damaged a lot faster. The relationship between vehicle weight and its damage to the road surface is exponential, not linear.
