Please.

BMW has cleverly engineered a system that fails to meet the obvious needs of the customer.

Yes, they may declare that you don't drive it 'properly' and hence the battery doesn't get charged...HOWEVER this is their fault. To sell a car that cannot be used like 99.5 of the other cars on the market is laughable.

I believe they would lose a class action accusing them of breach of an implied warranty of fitness.
