Saying “carpool” to the toll collector when one isn’t truly eligible for it seems to be a problem for the following reasons:
1) Sheker
2) Genaiva
3) Chilul H-shem (if caught)
If my concerns aren’t valid, I’d appreciate it if someone could point out why.
I don’t want to embarass the poster who suggested this – if I’m correct and this is a problem, perhaps that post can be removed.
