Analysis: The car is reasonable performance, handles reasonably well, though slightly sluggish. Brakes are abysmally far below standards and make the car harder to slow down than a cement laden double tractor-trailer combination. Noteworthy; the test drive was subject to surprisingly high levels of third-party idiocy. Clear skies, midnight.
Some things that come into my mind in the way of ideas: Gear shifting, switching highways/roads, stop-lights, and semi-trailer trucks. Doubtless these and more are likely already in the works since this is a demo, but here's my little input anyway. I like where this is going.
