One tip I can offer to tourist hiring cars is to consider the purchase of an electronic parking card called "EasyPark". You'd have to work out if it's worth while for you depending on how long you are going to be in Israel or if you make multiple trips.

It's about 100 Shekels and is a national card you can use at any blue/white street parking. You only pay for the time you've parked. You can get them at most gas stations, the post office. They can be refilled with credit when it's finished and it even allows you to carry on parking when you've gone into minus!

We bought one of these for my brother-in-law that visits and hires a car twice a year. Very handy!
