That is it.
When you walk regularly, you find paths from A to B that minimize your contact with cars to a level crossing or two. (Might be different in the countryside or in cities whose walkability is poor). So your chance of getting hit by a car are fairly low and you only really need to pay attention when you cross the street. For the rest of the time, you can afford to daydream or wander in thoughts a bit.
Once people learn to ride their bikes on pavements, it means the need for constant vigilance.
Biking needs its own infrastructure, separate from both pedestrians and cars. The needs and speeds are just different.
Bicyclists often have this view that they are above traffic laws and break them: >he will start riding on the pavement in places that are absolutely unsuitable for that, or on hiking trails that are absolutely unsuitable for that.
In my state, cars and bikes share the road and have to follow the same laws.
There is a stop sign at the bottom of a hill near my house, I have never seen a car drive through it, plenty of bike don't stop.
Bullshit. You notice reckless cyclists more because they're more unusual, that's all. The statistics for the rate at which pedestrians are killed or seriously injured show that it's overwhelmingly drivers who are putting you in danger.
