I'd just like to point out the reason for the poor viewing angles in modern cars. It isn't Tesla Motors' fault.
About 25 years ago, Honda embarrassed the entire automotive industry by building a lightweight car that simultaneously: 1) met EPA requirements for CAFE as a Midsize vehicle; 2) met CARB requirements for zero emissions; and 3) successfully passed all crash tests required by the NHTSA. As a result, the Accord became the best selling passenger car in the US for a time.
The Detroit Big Three protested. They complained, saying there was no way such a small car was 'safer' than larger cars were. They lobbied for the addition of three new crash tests -- all of which designed to destroy Honda products. So the offset frontal, side impact, and rollover tests were added for everyone in the industry. The increase in weight that happened because of this made for poorer fuel economy, smaller windows, thicker roof supports all around that blocked visibility. Hence, why mirrors are no longer enough, and cameras all around are becoming the norm.
CARB also reviewed the test results for Hondas. Indeed, all the required gases and particulates had been reduced or eliminated. So they made everything that was expelled at the tailpipe, even if it wasn't harmful in any way to environmental air quality, illegal, non-compliant as well.
Every car company that makes an attempt toward significant increases in fuel economy, combined with performance and decent styling makes the rest of the automotive industry 'look bad'.
