Everything, except the handheld communication devices from Star Trek (= smartphones). Oh and self-driving cars seem to be becoming some kind of reality as well.

Quite many futuristic views, not counting Mad Max and Waterworld kind of dystopias, seem to have believed that we would be using technology which uses lots of energy, like flying cars, hoverboards, generally flying to everywhere (even space) all the time, everything is automated etc. Sometimes this is explained by having come up with fusion energy or some other way to generate lots of energy very cheaply and pollution-free, but sometimes even this isn't required. Cars fly because... cars fly, no matter how much energy that would actually require.

Oh and the security concerns of flying cars is not really thought of either, even if the rush hour scenes in e.g. "The Fifth Element" and "Star Wars: Episode II - Attack of the Clones" give some glimpse of that. Two cars slightly colliding in mid-air...

What no movies (that I remember of) seemed to anticipate was that there will be a worldwide religious movement lead by an autistic Swedish girl, which demands that everyone must use as little energy as possible, and a society which resembles China in the 70s is some kind of utopia that we should strive for (ie. no cars (except maybe for the highest elite), everyone either bicycles or walks to wherever they want to go, people go from Europe to US to attend an UN convention with a sailboat, etc.).

Then again such future would have seemed kinda boring, as if going back in time a few hundred years, so no wonder it wasn't used in any movies.
