I agree, a floating tube won’t work. But a tunnel might. There is even a couple of islands halfway with a small village. But the other end is in Russia, with no villages in site for many, many miles! In other words, no charging stations.Anyone who had been in the Bering Sea in the winter could tell you a floating tunnel would be utterly demolished - it couldn't be put deep enough. The water is only around 100 feet deep.
I will wait for the CT and do the proper modifications, then the next one is the Model X(version 4680).I've heard of a couple of instances where Tesla has contacted CT reservation holders saying Cybertruck will be delayed, do you want to buy/lease a model 3 or whatever.
