I have installed RFID no less than 5 times on a few cars. Best reception is on the top of windscreen. They are 100%.
When installer test your windscreen with their scanner, they can tell if the tint is reflective type like vkool and 3M, then there's no choice but to fix the RFID on headlamp which is a compromised location due to the more upright angle and lower position on the car.
On my car with vkool, RFID is fixed on headlamp, success rate is low if you drive in too fast. The trick is to go slow at the beginning of the toll lane as rfid receiver is at the front of the lane, not at the back like Smartag.
The car that has Raytech tint and RFID on top of windscreen never had any problems with RFID and Smartag. Raytech tint is way cooler than any VKool or 3M tinted cars I sat in. Their specs exceeds the best of 3M or VKool specs iirc.
Another car has Hyper Optik, tint performance is just so so. No issue with RFID or Smartag either.
Due to Smartag and RFID issues, I avoid 3M and VKool on all my new cars.
I was using Hamel Royale before I replaced my windscreen and when the RFID installer tried placing the RFID on my windscreen, they couldn't get any reading, maybe due to the material used for Hamel.
Mind you, this was during the early adopter/guinea pig of RFID, so maybe the RFID they used back then was not as efficient as the current generation, hence the reason they could only stick on the headlamp.
When passing through those dedicated RFID lane, I had to drive below 15 km/h, and in some cases, like the RFID lane at toll Gombak, I had to stop very close to the boom gate before it can detect the RFID.
Like what you said, the design of CX-5 headlamp, with it very upright angle is not the best place for RFID placement.
On SmartTag, using Hamel Royale or V-Kool 40, I do have to slow down as well, maybe between 20-30 km/h, but not as slow as the RFID
