I imagine dedicated bike lanes would help with this, but at least where I am, there are dozens of cars for every bike, so I’m not sure how much sense it makes.
I don’t know that there’s all that much ‘hatred’, my road rides are by and large peaceful, but the cars that do seem upset by cyclists tend to be unwilling to respect bikes that are following the rules of the road; they don’t like bikes using a full lane and they will often break the rules of the road to pass a cyclist unreasonably quickly and unreasonably close.
One thing I’ve noticed about e-bikes is that they are increasing the number of cyclists considerably. I feel like this is very very good for cyclists, it’s making bikes much more present on the road, increasing the city’s interest in maintaining bike paths, normalizing bikes in traffic for powered vehicle drivers, etc.
