A lack of attention to the whole beginning-to-end process drives me crazy too. Especially because all those additions cost money to install and maintain, but the value they could add is lost when the doors aren't automated, or removed, or able to be opened with a foot.
On the other hand, after using motion-detecting faucets, automatic soap dispensers, automatic doors, etc for a long time, I catch myself standing in front of 'manual' doors waiting for them to magically open. Then I feel like an ass.
