We're bus users too now, much more fun than fighting with taxi wallahs. I'm afraid I've seen too many accidents and walking wounded to go within a mile of scooters, however,they're great fun and a great bargain, until the accident. When you're young you think it'll never happen to you, but with advancing years you realise, sometimes it does !
As far as the meters,they've had them for years but in twenty odd years in Goa, I've never seen or heard of them actually been switched on, and if this ever came off, they would never use them anyway
