I also noticed you posted http://www.mynissanleaf.com/viewtopic.php?f=6&t=21838. If you're going to do 90 miles roundtrip, even if you don't speed, L1 charging (120 volts) is probably not going to cut it if you wish to drive it every day to/from work, assuming no charging at the destination.
On L1, with any substantial amount of highway driving in your 90 mile roundtrip, you will NOT be able to replenish charge quickly enough at home overnight to start with the same state of charge that you began with the night before. At L1, ~1.44 kW comes out of the wall, and figure maybe ~1.1 kW makes it into the battery due to charging losses/overhead. If you charge for say 14 hours, then ~15.4 kWh would've made it into the battery. If you average 3.5 miles/kWh, that means ~54 miles added. Per http://www.mynissanleaf.com/viewtopic.php?p=101293, if you do 75 mph w/no HVAC usage on level ground, you should average ~3.0 miles/kWh, so 14 hours would add ~46 miles.
You will have to charge to 100% by Mon morning and once you find that you don't have enough juice on some day (e.g. Tuesday or Wednesday), you'll have take your other car until the Leaf has reached 100% (or whatever the acceptable level is) again. You'll need to do this or charge at your destination or have level 2 charging somewhere or supplement it with DC fast charging somewhere.
