Why not get a hire car?
I have driven twice the last 2 times I have been to the UAE.
Drove from Abu Dhabi to Dubai all over both cities and it’s pretty easy even from me who drives on the other side of the road normally.
Download an area of Dubai on google maps so you use no data and away you go.
I read on here of so many horror stories crazy drivers etc and yeah maybe 1 or 2 but honestly coming from London it was easy and much more free flowing even during rush hour. Yeah if you used to driving in countryside it will be a shock but compared to any major city one of the easier ones. Speed cameras seem to be everywhere so be careful. Not like UK where it’s pretty liberal really.
Can drive around at your leisure exploring. Petrol is so cheap and loads of free parking.
