My neighbours with fast sports cars and massive SUVs don&#x27;t see fuel costs as a big part of their transport choice. If they had any sense they would drive Priuses, Teslas and sensible Hondas, but they don&#x27;t.<p>Therefore, is it not possible to have supersonic jets for the likes of captains of industry, sports and other mega stars? Small, supersonic private jets? I can see a market for that. Lewis Hamilton would be first in the queue as would those Gulf &#x27;sheikhs&#x27; that have small fleets of Boeing planes.
