IMO not an unreasonable placement. The button is quite recognizable and right at the fingertips, unless it's been prone to accidental presses.
The trim of the dash in the picture, as much as luxurious it may be, reminded me of driving a desk, a walnut or ?mango wood desk... sitting in a comfy four-wheeled office chair. Also notable so many buttons on the driver side door, not sure for what purpose.
W203 nailed it. I'm a hazard light trigger happy driver, and I can hit it without looking, but if you weren't used to it you would find it immediately.
This is bad. Maybe it is because this switch is often used in Germany (when you approach a traffic jam on the autobahn you should press it), they though after a few of these incidents one would have figured out.
That one was even harder to find because it's not centered. In that image I noticed what looks like two Chevy bowties on either side of the steering wheel, before I found the hazard light button (spoiler: it's toward the passenger side and looks almost like the other buttons in the area.)
But model 3 takes the cake.
