Clothing does not require lapels, a tie or a collar to 'look good'. These aesthetic details are conditioned, not natural.
Clothing can be cut well, match and enhance the aesthetics of one's form, and not be a suit (ie probably be more comfortable and a better medium of personal expression as well).
Suits also carry a legacy of corporate identity, a state which many of us are automatically suspicious of... especially those of us who have to deal with corporate bureaucracy on a regular basis.
Ultimately, the valid point is... why should it matter what you look like? As pointed out, if you want a good engineer, get someone with qualifications. A suit is not a qualification.

Heh, your stock Subaru is only sitting on 11.7 quarter... lets see it do sub 7 seconds at the same price. The relevant number for talking torque is the 0-60, which is 4 seconds to the Subaru's 7+. That's where the limiting had to happen. The Tesla Roadster has acceleration figures that match cars significantly more expensive than it. Finally, take these cars and stick $20's worth of fuel in, then see if they make the same range as the Roadster on $20's worth of electricity :P

>>> A car that burns energy is still polluting, regardless of its energy source. Not all energy sources are equal. Converting gas to energy in a big, central, stationary engine and transmitting it is more efficient than lots of little, inefficient engines spending energy dragging themselves around the place. Electric motors are light. Batteries will get lighter and better with Automotive-industry RnD behind them. 'Green' energy storage infrastructure is easier to implement in a centralised framework (and probably more efficient as well). Regulating a centralised framework is easier than regulating lots of private individuals.
