I'd ride it and I ride routes like that weekly. Heck, it even has a passing lane, phenomenal.
tldr: take the lane.
Please take a moment to learn more about safe (not comfortable) biking strategies. If a car can see you and acknowledges you as relevant, then they move. They don't hit you because they see you, they hit you because they didn't expect a biker to be there (same with motorcyclists). Drivers are not set up for success to understand what they should do.
I ride in the middle of the lane and, while it takes a bit of time to get over the psychological hurdle, I found that drivers move completely into the other lane to pass with almost no harassment. Maybe one yelling dim-wit every other month but they always pass all the way in the other lane. I win ;)
I can send you videos if you'd like proof, it's kind of life changing once you try it.
Also, look into timing. Timing for long stretches and even short in-between lights can make a route even better. There's a "busy" section of road that I have all to myself every morning just because I hit it at ~7:15 (not 6:50 or 7:50 when late people are rushing to get to work) and wait for the left-hand-turn light to give a full light cycle before cars enter that section of road. Cars travel in packs, use it to your advantage.
This thread had some great info:
