A benefactor along with a scam - a free upgrade of Tesla's electric vehicle software helped people escape from hurricane Irma. But it was only available to customers who bought more expensive vehicles.

Tesla is one of the companies that apply price discrimination against their users. During Hurricane Irma, expensive cars received a saving update, and cheaper cars - no, - reports Guardian.

The incident occurred during traffic jams, when people were rescued from Hurricane Irma. One of the drivers in Florida asked the company to remove the battery limit from his car. The bottom line is that the electric battery's capacity is 75 kilowatt-hours, but the software limits it to 80%. The company launched a software update that allowed the battery to be used 100%. This allowed the cars to drive another 30 miles.

Since Teslas software updates are online, the company can make changes with one click of the virtual switch. There is no need to touch the engine, Everything happened as if in a computer game.

However, this upgrade touched only more expensive electric cars. Other users, as before, could buy this update for several thousand dollars. The incident is that the battery power of both expensive and cheaper electric cars Tesla is the same.

In the way the company did during the hurricane, experts see two violations. The first is that the company sold cars with the same characteristics at different prices.

The second is that she divided her clients into more "simple" and more "status".

It is worth noting that manufacturers of mobile phones and household appliances use similar marketing tricks to differentiate their products for a long time. "There is nothing new in this," says Dr. George Tech, an expert at consumer prices and executive director of global consulting firm Simon Kucera. "The only thing that has changed is that companies can now offer an upgrade during the product life cycle".
