Luckily, neither Balazs, his wife or his 7-month-old daughter that were on board that day got hurt (not even a scratch!). The police reported that the accident was caused by a puncture to the rear right tyre. Although the Bimmer was fitted with a TPM system (Tire Pressure Management), according to Balazs, the system never gave any warning whatsoever.
