Road road trip is a road trip :D No comparison.

But bear in mind, the road conditions are not great. Especially from Salwa to Silah border (UAE). Once you reach UAE, its a smooth ride from there onwards.

BTW, Speed limits are insane on these roads i.e 140 kmph. People normally drive at 160 kph. The camera flashes at speeds over 160 plus. There is a leverage of 20 kmph. Though you would be overtaken by Landcruisers flying at 200 plus speeds. :D

The choice of vehicle is important. Try to go on a 4x4 or SUV. The road distance is less than 670 km. It takes practically 8 hours for all border clearances and stuff to reach Dubai.

It is worth a road trip :D
