44mi x $.535/mi[1] + $5 bridge toll = $28.54 per day to commute to work.
That's $~628/mo all-in to commute via car. My additional housing costs in the peninsula would easily be more than that for equivalent housing (2br SFH).
Commute is typically 40m-1:10 to work and 28m-1:10 back, depending on when I leave (and time of year). I normally head to the gym after work which means I skip the heaviest traffic on my way home.
Averaged, commutes are 40m each, which was my door-to-door time when I used to commute to the city via Bart (admittedly, not as pleasant).
[1] Based on IRS mileage rate.
Its a reasonable rate to reimburse employees for driving their own vehicles for work by (I'd estimate its about 95%ile of expenses), but a poor rate to estimate general car ownership costs by.
