Freeways

I'm still not good with Freeway entrances and exits. Getting on, the entrances will all be on the right hand side, with the directions of the freeway described as "North" or "South". Seeing as most of the freeways I use run MUCH more east-west than north-south this is a little confusing. Often I can work it out if the sign says "San Francisco" or not. Also the nature of the entrance ramps that sometimes curve through 720 degrees means you can't tell where it is going until you get on it. The same goes for exits. The whole system actually beats the freeways back home because there are no traffic lights involved anywhere - I'm just not used to it.
