Seating in tandem in vehicles

That's why motorcycle safety classes teach to occupy the side of the lane nearest to traffic.

When I'm traveling in a multilane highway, I ride closest to the vehicles in the lane next to me. Not only are they able to see me in their mirrors, and are more likely to watch where they are within their lane, but it provides a buffer that I can escape to should they begin to cross into my lane.

With oncoming traffic, I generally favor the inside line, and only move to the outside just before passing by.

If there's a string of oncoming cars, I favor the outside line to give everyone in the line maximum opportunity to see me.

All of these strategies can be applied while driving other vehicles, but hardly anyone thinks of such things. Most aren't engaged in the driving process, which is why they get hit by people running red lights when they could have avoided the accident had they simply looked.

An option of having one seat a foot or so behind another has been used in some small aircraft. This means less width needed for elbow and hip room while maintaining ease of communication.

Semi-tandem?

The 1938/39 Porsche 60K10 Berlin-Rome racer used this a strategy to minimize frontal area.

I like the idea of tandem where the legs of the rearward passenger can extend into the hip area of the forward seated person. This places them as far forward as possible, and utilizes the otherwise void space in the seating area caused by shoulders being wider than the seat.

I'm wondering if commercial airline seating could be even more efficient or comfortable by offsetting the rows or creating "straddled" seating? The big discomfort with commercial seating is inability to extend the legs. Straddling would eliminate that discomfort at the expense of some of distance between the person seated ahead. I'd take that tradeoff.

Some good posts here. Just looked up that Porsche Berlin Racer. Must have looked quite advanced at the time.

In that case you probably haven't seen the Volhart-Sagittta V2. Similar era and aero but it's a four passenger vehicle.



In the rear quarter window you can see the top of the rear seatback. Imagine a head with a German helmet above that. It doesn't give up much to the racer and there were two instead of one (). 90MPH on 21 or 25 HP.

The tulip panel below the windshield makes the cabin a filleted half-body of revolution.



That rear seatback again.

Better Cd than a Prius.

IIRC the Renault Twizy resorts to this layout.

Safety regulations (and maybe the ADA too) prevent this.

Porsche Type 64 – A Star is Born

The 64 was to have an aluminium body, and the wheels were fully covered with removable alloy panels. Due to the event being a long-distance road race, Karl Fröhlich designed the car to carry two spare wheels in its nose, a move which meant the standard fuel tank would have to be relocated further back on the passenger side. With the fuel tank now protruding into the passenger area, this resulted in that seat being moved towards the centre of the car and 30cm further back than the driver’s seat, in a staggered formation. Looking at the roof structure from the outside, it can be seen that the dome-shaped cabin was both low and narrow, making the interior uncomfortably confined.

I like Aerohead's explanation better.

This is not the Berlin-Rom Car. This is Porsche Typ 114.

Super the Blueprint with the Body Cuts.
