No porn at McDonald’s, Starbucks; SoftBank buys ARM; a Tesla fix

The two chains are implementing filtering technology that blocks customers using Wi-Fi from accessing porn sites, in response to a campaign by antipornography groups Enough is Enough and the National Center on Sexual Exploitation.

Tesla Motors CEO Elon Musk says he’s optimistic that a software update can improve his cars’ Autopilot system.

Tesla has been working on changes since May, after a Model S sedan failed to sense a tractor trailer in bright sun and crashed into it, killing the driver.

Musk tweeted that after talking with Bosch, which makes Tesla’s radar sensors, it appears “significant improvements” can be sent to drivers through over-the-air software updates.
