Some system, especially in India, appear to be relying on essentially switches rather than deceleration sensors.

The failure rate of airbags is according to most studies well below 9%

Even I suspect that as well. However, hopefully more expensive vehicles should have deceleration sensors. I wonder if switches for airbags are still produced today as that is a very outdated technology.

Oops, my mistake. Failure rate is well below 1%.

We can't expect airbags to deploy in this situation, nor is it the car or manufacturer's fault. If a service centre guy said, “It’s because you did not collide properly”, there's possibly a modicum of truth in it!

Maybe manufacturers need to relocate their airbag sensors for airbags to deploy more easily - but then there would be so many airbag deployments in mild shunts, that we'll need another section, not a thread, to report all those cases!
I am quite shocked. Why can't the manufacturer add enough sensors to cover such impacts. Could there be a sinister angle behind the reason they don't?

Difficult to answer that with conviction, but economics does have a role to play.
