Earlier quoted context omitted.
Same in Netherlands. Google Maps has recently become worse and worse. Small pedestrian roads are missing, and the navigation is getting stupid. Google applies the one-way limitations for cars also on cycling routes.
To go with the comparison mentioned in the article though, Apple maps doesn’t even have an option to cycle at the moment. I never use it in London for just that reason. They’ve decided that it’s more important to add ride sharing as an option before cycling in what I can only assume is a product of their being in suburban America.
Close, but imho is has more to do with liability, a fear common at all american companies. Car drivers are licensed. They can be expected to obey traffic laws. So when google sends them down the wrong way on a one-way road, nobody blames google. They blame the adult who listened to their phone rather than the signs. But bicyclists are not licensed. If google says that a road is open to cyclists when it isn't, and something bad happens, few will blame the 12yo unlicensed cyclist just following their phone's directions. This is why google, imho, seems to be limiting bicycle routes to those areas with the most clearly defined paths, preferably separate from roads.
And the one-way thing for bike routes is likely based on the widespread understanding that bicycles on roads must obey all the rules that cars do. Going the wrong way on a one-way road is illegal in many areas no matter what vehicle you use. This may never be enforced, but google's legal team probably isn't willing to depart from the letter of the law.
