It' hard to say when just looking at the artwork as it sits now. It all depends on the scale of things. I think the style can be maintained with tandem seating, but some features would have to be scaled different than others. The wheels for one thing are not realistic, they need to be smaller in the space, and the driver windshield would need to be slightly taller and extend slightly more forward, and slightly more back, maybe no scoop on the top... Then if it were electric, yes two seats are very possible with these proportions. In ICE, then just taller and more to the back, that could work too with a small 1200cc opposed 4-banger. I notice that especially now, current conceptual art works are very fantasy oriented, a pet peeve of mine. Sure it's cool to do a futuristic look, but hey, the driver has to actually see, the wheels have to roll, and there needs to be room for things like a drive train. If it ever became manifest in real-metal could those styles be maintained? Very often not. When I'm morphing from the original I do try and push it closer to realistic with a thought toward those space requirements. Electric drives can be displaced in many different ways, so that gives me a bit of an excuse, as it did in this case. Sometimes I receive a benefit in that something that can NOT work as a 4 wheel super-car, can be made to work realistically as a 3 wheel autocycle. I am however avoiding most of those spiffy-SIFI-super-non-wheel/wheels. (with exceptions). And especially those where the driver's eyes are actually below the top of the wheels. It's all in good fun, well everyone needs a hobby! For now, this has been one of mine.
