I do believe it is because of the 3rd world status of this otherwise wonderful Palestinian land my dear friend.
Sounds like these lovely but simple-minded Jewish people desperately need our care and guidance, otherwise their future will not look very bright, I am afraid.
Cars and all vehicles use gas, but these splendid people do keep many religious superstitions locked inside their closets, like certain days of the week, the "spirits" do not let them flip electrical switches or even open or close their window shutters or doors.
So actually, gas prices does not play a huge part in their lives. After all most of them walk to wherever they want to go to, which is a healthy thing to do nowadays plus, it saves them seven dollars on their daily transportation expenses and that's smart!
Thank you for sharing
