Today you can hardly tell when something is remade, because so often it is remade by code. When you press your foot down on your car’s accelerator, for instance, you’re no longer controlling anything directly; there’s no mechanical link from the pedal to the throttle. Instead, you’re issuing a command to a piece of software that decides how much air to give the engine. The car is a computer you can sit inside of. The steering wheel and pedals might as well be keyboard keys.

The world’s second-biggest economy, which has vowed to cap its carbon emissions by 2030 and curb worsening air pollution, is the latest to join countries such as the U.K. and France seeking to phase out vehicles using gasoline and diesel. The looming ban on combustion-engine automobiles will goad both local and global automakers to focus on introducing more zero-emission electric cars to help clean up smog-choked major cities.

Water companies are not obliged to supply all the water that people would use if it were free, nor are power companies expected to provide all the free electricity that customers might want. But many cities try to provide enough spaces to meet the demand for free parking, even at peak times.

Parts suppliers in the American South compete for low-margin orders against suppliers in Mexico and Asia. They promise delivery schedules they can’t possibly meet and face ruinous penalties if they fall short. Employees work ungodly hours, six or seven days a week, for months on end. Pay is low, turnover is high, training is scant, and safety is an afterthought... Many of the same woes that typify work conditions at contract manufacturers across Asia now bedevil parts plants in the South.

Smart stoplight systems, formally known as adaptive traffic signals, allow stoplights to memorize traffic patterns, communicate with each other and adjust the timing of green and red lights to improve traffic flow ... Using technology to boost traffic flow is much less expensive than widening roads or building transit lines, and those solutions typically face environmental hurdles and community backlash.

In the last year, Uber has launched partnerships with transit agencies across the country...Using Uber Movement, a tool akin to Google Trends but for traffic patterns, users can enter locations and date ranges to measure the traffic impact of, say, a lane closure or major highway disruption, a metro shutdown or a new road. The tool could benefit urban planners or other people looking to analyze travel patterns...Other similar tools used by urban planners are not free.

Employing a human welder in a factory in the U.S. costs about $25 per hour including benefits, according to a 2015 study by the Boston Consulting Group; that drops to just $8 per hour for a robot, including installation, operating costs and maintenance. By 2030, "the operating cost per hour for a robot doing similar welding tasks could plunge to as little as $2 when improvements in performance are factored in," BCG said.

The long-promised software will update Tesla’s existing semi-autonomous driving features, and will include speed matching technology that will help Tesla cars to keep pace with traffic, switch lanes, and exit and merge onto freeways, among other uses ... The speed-limiting software will kick in on roads and non-divided highways, where Teslas will have no choice but stick to the precise speed limit. On freeways, however, Tesla will merely stick to its overall speed limit of 90 miles per hour.

Some cities are deliberately reducing the number of lanes on major roads to make room for bike lanes and wider sidewalks, while cramming more cars into a smaller space ... Faced with ever-increasing traffic jams, South Florida's public officials have come up with a plan: Make it worse. Instead of fixing the problem, government officials are deliberately adding to it in hopes we'll all walk, ride the bus or take the train.

A study done by physicians in India says that strokes are rising sharply there, projecting that one in six Indians will have a stroke in their lifetimes, and one-third of those stroke victims can blame air pollution ... about 300 million children breathe what is considered to be “highly toxic air.” Nearly three-quarters of those kids live in South Asia, where vehicle pollution, factories, naturally-occurring dust, and slash-and-burn agriculture are the leading culprits.
