Following dramatic rises in the cost of fuel, esure has shown that many drivers would stop driving if prices reached £1.75 a litre.
It noted that while petrol currently costs an average of £1.15 per litre, the uptake of other forms of transport has been slim.
Research from the group found that for nearly a fifth (19 per cent), prices would have to breach £2 a litre in order for them to opt for other transport methods.
However, more than three quarters (76 per cent) said they were more concerned than they ever had been about the effect that petrol prices are having on their pockets.
Mike Pickard, head of risk and underwriting at esure
car insurance, commented: "In a bid to conserve as much petrol as possible, simple changes to the way you drive can help prevent your car from guzzling up your hard earned cash."
Earlier research from esure has shown that 81 per cent of under-25s would consider buying an electric vehicle in an effort to avoid the effects of rising fuel prices.
