Splitpair In my less than humble opinion the NJTP made a huge mistake by forcing Tesla off of their roadways, if they want to attract EV drivers they need reliable EV chargers and Tesla provides just that.
On the most heavily travelled part of the Turnpike (between Exit 6 and the northern terminus at the GW Bridge) there’s no real viable alternate route.
US 1 is probably as slow as US 1 is down in Florida.
There is the Garden State Parkway along some of the route, but that also has tolls, and in fact the Turnpike and Parkway are now under the same management.
In other words, the NJTP doesn’t really need to attract anyone—it’s a pretty captive audience except for southern NJ where I-295 is a free alternative.
