I also would love to see more safe ways to ride bikes, but I don't see it happening anytime soon.

"Dump legistration" is the way it is as increasing the power and speed limits with inadequate infrastructure can significantly increase risk for pedestrians and bike riders, likely more than risk posed by cars.

Most places already have adequate infrastructure for cars to be safe enough.

Infrastructure changes such as adding more ebike only lanes need to come first, and this will cost a lot and even infeasible without first reducing the number of car lanes. This will result in conflict of interest between car owners and people who want to introduce such infrastructure changes.

Conflict of interest can only be resolved by politics, and it will take a long time for politics to work out as changing people's perception generally takes a long time.
