And when I'm in the middle of nowhere at midnight with a broken mobile... how do you propose getting in touch with the RAC and letting them know where I am? :/
So you're going to carry all your tools with you, along with your Haynes manual and encyclopaedic knowledge of the stuff that's not covered or wrong? Because, after all, you won't be able to access t'interwebz with your mobile all borked.
OK, good luck! :)
