>- The heater's blower knob has an a/c button in the middle of it so that you accidentally hit it with the thumb while adjusting the airflow - then wonder 5 mins later why the car isn't getting any warmer.
>- When you cancel the indicator it flicks over to the other side if you don't do it very delicately.
>- There is a central armrest, and one on the door handle, but if you can put your elbows on them you can only just reach the bottom of the steering wheel and your arms are practically akimbo.
>- As I said, cos I need the seat way back my arms are practically at full stretch to reach the wheel (at 10 before 2) with all the stress on the shoulders that entails (and memories of the trapped nerve in my neck the other winter).

They seem to have perfected the reverse ergonomics :). I used to drive a Renault 4 and a Peugeot 504 (from the eighties) and both were perfectly comfortable, French style. Even a 2CV was nice to sit in, and the only objection was to the, ahem, suboptimal heating.

What has the world come to when the French have started making cars which cause discomfort...

>- The bonnet (hood) falls away in a curve from the wide windscreen (windshield) such that you can't see it or perceive the width of the car when in a narrow passage or parking (very disconcerting).

It can be concerting, if there's an assortment of metal trashcans where you park.

This one, however, is not typically French, nor just Peugeot. It's pretty much any car nowadays - the rear end is getting taller and taller, and the front end is becoming completely cornerless - so you have no clue how far these corners are. In any car made in 60s-80s I knew exactly where my corners were; after that, I have to use outside clues, like reflections in shop windows, nearby cars, how far apart are the reflections of my headlights in the rear of the car in front of me etc etc, because I don't have any direct clue. All my corners are beyond horizon.
My trick for curbside parking is to keep the curbside mirror low enough so that I can see the pavement's edge. If I can see my rear wheel, perfect.
