No, one of the worst places.

The key to RFID success is:

1) Must be on completely flat surface

2) As far away as possible from metal surface

3) if possible, as far in front as possible

4) as high up as possible

5) as forward facing as possible, left /passenger side oriented (there are some readers are now placed beside instead of high up ceiling)

6) behind number plates was a popular placement as it'll allow safeguard against road debris (me and my wife kena before stone bullseye damaged the RFID antenna, the center chip, or both)
Why i say was, it's because of point 5

Close to roof or a pillar (or both) that's metal, and it's a distance away from the front bonnet

Not too mention, not all glass surface is properly flat.

If your car bonnet long like mine (GT86 coupe) then your failure rate gets very high since you'll reach the toll gate too quickly and the RFID reading will just stop and prompt your failure. That's when you'll need to reverse.
