Any chance of getting Google Maps to ever say, "Avoid Dirt Roads" when recommending bike routes?

Yes, I know other apps exist other than Google Maps, you don't have to tell me.

But I was planning out a possible bike tour, and Google Maps just desperately, DESPERATELY wanted me to go for 80 miles, mostly on dirt, up and over mountains, rather than just ride 50 miles along the shoulder of the highway with a simple, gradual climb and descent. As it is, this is in a pretty remote area, even along side the highway - no services - so if I were to have a major mechanical/medical, I would want someone to see me and help - and if I did that crazy 80 mile route in the middle of no where, they'd only find my bones being picked over by vultures and coyotes. I finally just told it I was in a car, and it settled down and let me know that yeah, it's 50 miles, something I actually could ride in a day.

If they can do "avoid highways" and "avoid tolls", they certainly could do "avoid dirt" for bicycles. How can we get them to make this change?
