and it shouldn't smell. i'd be most worried about your mother getting charges brought against her. if she doesn't know about it, you're putting her at risk by bringing it. IMHO either tell her or don't bring it. if she does know, then like i said you don't want it to smell, don't put it in the glove box, find somewhere very discreet. most likely you'll have no problems, but you never know. can't be too careful in our hypocrytical country
