Did it matter that the wheel disappeared in the Middle East?

Still the basic economic superiority of the camel prevailed. A few wagons reappeared under the Turks. More significantly, the Ottoman Turkish expansion into the Balkans did not spell the end of wheeled transport there. However, in general the use of the camel remained all-pervasive until the advent of European influence which stimulated the building of carriages for use in cities.

Then came the automobile and the end of the contest was in sight. There were setbacks, of course. In World War II, for example, lack of tires often forced the Arabian American Oil Company (Aramco) to use camels instead of trucks. But that was temporary. Today even Bedouins keep a truck parked outside their tents. The day of the camel is past, and whoever laments its passing would do well to remember that 2,000 years ago someone else was lamenting the passing of the ox cart.
