You bring up a good point. I have often wondered why windows on cars could not have a moisture detection system to activate the motor to roll up all the windows on the vehicle when there was no indication of passengers present. I am not sure why it is not in use. I like the concept of the tinting roof top though it might be very costly.

I think some premium systems might.

Now, for a full roof, it might not be doable when you are flying down the highway.

I'm surprised they haven't built a convertible top like the old roll top desks. That type of mechanism might have enough rigidity to open and close while travelling at high speeds.

A few convertibles do allow you to open and close while driving, but they specify speeds of <35 mph. The truth is though, it's just a button. If you're going to leave your car by itself, you obviously close the top to keep people from reaching in. It's a patently bad idea to have the car automatically remodulate the cabin while you're driving. The driver can clearly see rain droplets or feel chilly, all they need to do is press a button. When they're not in the car, it's silly for more reasons than just the weather to leave the top down for an extended period of time.

It wouldn't be the first cute, but somewhat useless feature on a car though.

I love convertibles, but I see no benefit to this. I often commute through rain with the top down at highway speeds and I like it. I also leave the top-down in the driveway overnight often, so I can enjoy it the next morning without the hassle.

I own three convertibles with power tops that say in the owners manual that you must be stopped to operate them. Two of them require the emergency brake to be set.

The manual top-convertible (Mercury Capri) I own actually requires that I stop, switch-off the engine so I can use the trunk-key to unlock the top-storage cover.

But I agree with the premise that the top should be able to deploy or remove in-route--just no-one has designed this.

In my classic Mustang, I can and do put the top down at slow speeds, but not up.
