Good idea, but the part about still being able to get in your car when parked close together won't work. Nearly every American is twice as fat as that gap they left. Some of the cabooses I've seen this holiday season wouldn't stand a chance.

why should one doubt this? the BMW Z1, which came out almost 20 years ago, had drop down doors similar to these.

it's all brilliant engineering. one of these cars was recently found on ebay. don't remember if it sold or not

This was done before. Lincoln built a car prototype like this but didn't think the market was ready for it. They ordered the destruction of the prototype, but somehow the orders weren't carried through. :-) The prototype was sold a few months ago on eBay! See:

Normally all car become dirty after a few days how would this car look with a permanent cleaner or smudged door (I don't know if the system works without a touch), If you look to the door from inside you will see no design at all everything is like a stretched fabric on the face of the interior door and that doesn't look too secure or beautiful. And what if is raining the entire interior door will become a wet or dirty after the door was opened?�And of course you must be a ballerina to propel your self outside the car�.And the result is that this door cannot work for the real sedans world. Sorry.

So is the outer paint work exposed still as it is underneath the car? If so, all it will take is a slightly uneven surface or rock to leave a great big scratch down it

I think the reason we don't see this on production cars is the cost. Not only would it cost more in electric gizmos to get the door moving up and down (an thus introducing another fail point to something that works reasonably well already) but most cars need a B pillar for a reason! You'll probably find that these cars weigh a ton since they've had to reinforce the chassis so it doesn't fold up. As an example the 2009 Camaro has had a B pillar introduced since it wasn't cost/weight effective to build the DLO featured in the concept. Now whilst this kind of door is then impractical for side cabin entry, it'd work quite well for a rear tailgate on an SUV (although forget carrying a spare since it'd take up a lot of space under the rear). But then since Americans (and myself) love their split tailgates that you can park your ass on whilst chilling out with friends we wont see this happening anytime soon, well except for Pimp My Ride.

And would someone fix the template for this site so your comments don't run outside the pagewidth!

i used to work for this company... they used to call themselves joalto design until they embezzled too many millions from their investors, w/o coming up with any product. the doors were very problematic and we only drove them to demo's in the summer... to CrisX's point, yes, if they were covered with dirt it would destroy the finish and any sort of ice build-up in winter would render the rocker-panel-skirt useless and cluttered.

I'd hate to be in an accident riding in this death trap. With the B pillar gone, another vehicle could literally impale this car in a side collision.

Can you imagine being in a situation where the electrics failed... or where the car battery died.. how would you get out...?

E.g. If you were in a head on collision and the door was structurally damaged or a side collision where the door was damaged... how would the door open?

Great Idea..
But Not safe...

Listen, this is fake as you can see problems with the video near and around the door. Although some cars exist that similar features, these are fake, the British accent is not very good on the guy and the cars all have left side drivers as well as the license plate is not European in style. Clever, but not quite

I think the accent is just to try to sound like a butler - it's not a real British accent, anyway.
