40 mi avg daily is just about the limit on L1. You can probably get 50 mi (5 mi per hr charge x 10 hr overnight) or maybe even 60 mi in a mild and non-hilly area (not yours). If you come straight home from work every night, plug in immediately, then perhaps you have a maximum of 14 hrs L1, maybe 70 mi. That's ok once in a while, but it doesn't allow for much of a "after work" life if you do this every day. I have done about 150 mi on two contiguous days using L1, but it took some planning. If you get behind on your charging on L1, you can't catch up, and the only option is to cancel the trip or use another vehicle. This has happened to me about three times in the past year (once cancelled, once delayed start, once ICE). RT to work is 8 mi so I don't worry too much about my constant L1 use.
