That's a luxury problem. It's like saying that you're better off without ECC because you don't have to deal with memory corruption. With a single sensor, you still have to deal with inaccuracies, the difference is that with only one you just don't know if you have it or not.

the luxury is adding every kind of sensor without considering cost, engineering time, computing power, etc.

complexity is extra-linear, so you have to have to do the cost-benefit analysis to determine if it's worth it. and it may well be, but my point was that it's not a knee-jerk answer to always add more sensors. there is clear benefit, but is it worth the cost?
