New York to London in the family wagon. Just 215 hours — figure 3 weeks each way.
Never say never, but really, what’s the point of this project? Anyone who wants to go from New York to London and have a car there just needs to fly and rent, also you then have a car that is designed to be driven on the left.
One thing you would not want to try is driving in England with a right-hand drive car. That would be suicide, it’s tough enough with those narrow roads and the roundabouts if you have a British car.
However, the main stumbling block would be that Siberia is almost entirely devoid of towns and services from the Bering Strait to wherever this road would meet up with the Trans-Siberian railway corridor, which would be a long, long way. And this is the coldest part of the northern hemisphere in winter. There are places that routinely get down to 60 or 70 degrees below zero along that route.
A road might get some industrial transport use but as a tourist route, I can’t see that working.
