That'd be me. When I bought my Mitsubishi Lancer Hatchback with manual transmission in the US, having a working handbrake was a jarring experience. My friends spent a lot of time helping me break my habit of using gas and brake pedals for keeping the car balanced up hill - I can still do it well.
I'd like to note that this feature wasn't exclusively limited to Ambassadors, my dad owned a Maruti 800[1], and a Fiat Padmini[2], neither of those had working handbrakes AND my dad managed to install aftermarket LGP kit in former and a datsun diesel engine in latter. Both modifications made it an interesting driving experience. These days when I'm driving my automatic transmission car on a freeway with no potholes, cows, I do get some flashbacks of driving in pouring rain with water creeping up from floor and being scared out of my wits.
