You'll be able to do it, no question.
My wife and I regularly do commutes to/from San Francisco to Silicon Valley down 101 or 280 - 70 to 75 miles - and we never run into any trouble. Yesterday, I did a 71 mile commute after a full (extended) charge - 2 passengers, AC on the whole time, highway speeds - and I was at approximately 45% SOC when I returned (ie, 45% of the battery remaining). My wife usually does a standard charge overnight (ie, she starts with the battery 80% full), does a 75 mile commute, and ends up at home at around 20-25% SOC. Our RAV4 EV is over a year old with over 18k on the odometer, so this is *after* any battery degradation this past year and substantial mileage, which has seemed negligible.
The one thing to be careful of is very cold days. The amount of electricity used to both heat the battery and the passenger compartment can substantially limit range. Even then, you should be able to do an 80 mile commute at highway speeds from Berkeley to Redwood City on a standard charge.
When we first got the RAV, we did my wife's commute on the weekend, sweating the whole way, worried we weren't going to make it. The range anxiety pretty much ended that day - the RAV makes Bay Area commutes easy.
