driver tried to race the tide instead of going over the bypass , an extra 5 minutes. imo he has driven too close to the base of the rocks where there is always a deep hole caused by the wave action, once you stop in the surf waves the sand washes out from under the wheels and sucks the vehicle in. If the tide is dropping you may have a chance but in this case tide was rising so there was no hope. One tide over a vehicle will destroy it. more so if you have big seas. First and most important thing about beach driving is not to race an incoming tide
