I can't solve the road conditions, but a good e-bike makes a long commute much more viable. At least once a week I do a 42 mile round trip commute on my ebike. I bought a 52V, 500W mid-drive motor and battery kit from Luna cycles and put it on my hard-tail. It has a 1 kwh battery on it. I could probably do the whole trip at almost 25 mph on one charge, but to help maintain long-term battery life I bring the lightweight charger with me and top it up again at work before heading home. Since I built the bike myself there's no governor on it so it will go around 30 mph in the flats very easily. But I set it to a lower assist level and pedal. I basically get the equivalent of the workout I would get if I were riding let's say 10 miles each way on a regular bike instead of 21 miles each way on an e-bike. Takes me an hour each way. In the afternoons during rush hour I actually often get home faster on the e-bike than I would have gotten home in my car.I miss those days. I used to commute to work via a bike path next to my apartment, ride out to the gym, and pick up groceries on the way home.
Since moving out of the city, cycling is just for exercise and enjoyment only. My work commute is 50 miles round trip, so that isn't going to work. My nearest grocery store is only 14 miles round trip which is fine, except bikes are always being stolen, so that is a no-go as well. The ride itself would suck anyway because the expansion strips on the highway shoulders around here are about 3 inches wide and every 20 feet.....might as well be riding on a train track.
I do need to get out and ride more to shed some winter weight, but that is all the bike is good for these days.
Luna Cycles is based in S.F. and they sell some nice kits.
