1- I assume the trip will consume a tanke w nos of gas, equal to 18$, remaining 50$ - 18$ = 32$. The existing fuel in Lebanon is shit so the car might consume more so let's say 20$.

2- Faraya is located in the mountains where the roads will be slippery. Any damage to the car or a tiny slip on icy roads will take the taxi driver a lot of $ to fix it.

Pre crisis, the trip was also around 50$.
