Not necessarily as cars, which would be a hybrid, yeah that would be stupid. But short range flying vehicles make sense. I think your argument is about steering, but they would fly automatically. I think it makes more sense to have them for some people which would be flying from suburban areas or between one side of the city to another.

I'm not so sure, I don't think they make any sense energy-wise and would be less safe than ground vehicles. The amount of energy for a plane to take off is far greater than the amount it requires to stay in the air. The only short-range flight I expect to see are small electric powered planes for short flights, we've already seen these spring up in a few places in the US.

They wouldn't be planes. I've seen videos of people that have flown on basically drones.

This is what I meant, but drones is such a bad term anyways, since the drones in nature die after flying.

Drones are great but not exactly stable. There are just too many random variables to predict for flying cars to ever be safer or more efficient than travelling across the ground. There's not really any advantage to doing so and there's all kinds of problems it could cause

It's not about everyone using these, but a minority who can afford it and maybe needs to be somewhere. Time can be more important than anything else.

I have several arguments against them including:
- Noise pollution and wind currents at landing and take off;
- Safety. Congested airways would produce many more accidents in 3D than 2D highways among vehicles. Also intoxicated drivers becoming suicide bombers crashing in tall buildings. Also it would be harder to institute traffic rules that establish priority because there are no fixed routes.
- It would ruin the city landscape making it cluttered and chaotic for pedestrians.

The noise of electrical motors isn't that high, and they might land and start from buildings or special stations. Congestion and accidents are not an issue if it's expensive and with autopilot. They won't be passenger controlled. I don't understand you last point.

electrical motors are completely silent, but propellers aren't. Even if autopilot is perfect, it would only be safe if manual control is always forbidden and i doubt people would agree to that.

They will agree to it, there will be no other option. That's exactly your strawman: Saying they won't want what they could get, and what they want they can't ever have. But it works if we reverse it. They want and will take what they can get, and get over what they can't have.
