Quoted from aerobert:

I showed my colleague who is a mechanical engineer my pinball machines. He's 28 or 29 years old and was never into pinball. Brand new world to him. He shook his head and chuckled and could not understand all the solenoids and different mechanical solutions. Everything was so archaic to him. He asked similar questions, why sensors, electronics and servos and stuff wasn't used instead to have more controllable logic without high voltage stuff. I honestly could not answer him.

Servo driven flippers would be neat but I'd like to see your friend come up with a solution that can match the torque, speed, and cost of a solenoid.

Quoted from Sonny_Jim:

Inductive switches don't work reliably when the ball is moving fast

I sell sensors for a living. It all comes down to cost vs performance. I think the missed balls have more to do with the range and how the sensor is located under the playfield. Like Mike said, inductive sensors with enough range to detect the ball through a 1/2" playfield reliably will be much more expensive than a micro switch. It's also more complicated to locate because any other metal in the vicinity of the sensor and the iron content of the ball can affect range. It looks like Heighway designed their own sensor to keep cost down and also counterbored the backside of the playfield to reduce range to the ball. It's not perfect, about 1 ball out of 5 gets missed on my Full Throttle's fast inner loop (all the other sensors work 100%). There is some adjustment which seems to help but there is just too much variability to get it up to 100%. I also believe the CPU struggles and the scan time between inputs may be too long. Having an off delay built into the sensor would solve this problem. This is all just speculation on my part.

Quoted from MarkInc:

When I spoke to Romain Fontana from Heighway (pre 2016) he said the sensors were on their own boards - self calibrating and buffering their data (independent from CPU scan rate)

Hmm then there must be a way to "teach" the sensors. Haven't found that in the menu yet - I'll reach out to Andrew HeighwayPinball and see what he says.

Looks like there's a separate cutout in the cab for a bill acceptor?

I wonder if Stern knows they have posted me on their Facebook page?? LOL

I wonder if Howie Feltersnatch knows Hugh Jasoul?

Actually about the only reason I have left for SAE tools is for my pinball machines. Everything thing else I own including my US made cars use metric fasteners.

Never mind, too soon
