One should be careful in extrapolating sales numbers from the coasts to the rest of the US. After a certain saturation level is reached in those areas, EV penetration/sales growth will likely slow as it will be a more difficult sell in much of the country for some time. Also, the growth rate of EVs in European counties can not be used as good examples of what to expect in the US. European counties are generally more widely developed than much of the US, they have generally shorter drives and higher population density makes it easier to justify charging infrastructure investment. They also have stricter laws regarding pollution and populations that are generally more environmentally conscious when making purchasing decisions.
