Or go tee total on the weightloss journey. Saving money and lose weight faster. nope, seemingly no telling them that either.  Just a hunch of mine but eating behind the wheel and weight must correlate as they need more calories and, well, they're fat, I see them eat too... so distractions (by eating) causing crashes could lower by shaming that behaviour and also get some more fatties losing weight. 2 for one bonus shame! All insurance premiums should then come down (in theory, in reality insurance companies would keep some of the reduction).   I also try not to eat anything behind the wheel, but that's just me.  Yeah, I fear maths on food budgets might be just the usual pay cheque to pay cheque lifestyle with shit on credit cards too. Long term budgets... naaaah
