From videos I have seen the Charlottesville attack was very similar to the NYC attack.  The car approached the crowd at a slow speed initially then purposely sped up and ran into the protestors. The person driving that car was also part of National Vanguard, a white nationalist organization. https://en.wikipedia.org/wiki/National_Vanguard_(American_organization)   They say he wasn't but there are pictures of him holding their shield and protesting with them.

So you have two people that are part of terrorist groups, willfully attacking and trying to kill innocent people because they disagree with them and want to cause terror.  The only difference is that getting the full picture in the Charlottesville took some time while the NYC attack didn't but once you see the full picture of both, they are pretty similar.
