If you drive much more on the highway, idling never happens, however in traffic congestion, you often idle a lot, which puts enormous heat on the engine. The best life to do is to take a look at the timer on the website traffic signal and also shut off your car appropriately or keeping the vehicle in neutral and also giving some added Revoltions Per Minute to the auto so that idling doesn't occur a lot.
However today, you don't have to do that! The idling you do on today's automobile burns valuable gas and leaves energy residue on the cylinder walls that stick to it since the cylinders typically aren't moving as quickly as they usually do. This pollutes the engine oil with carbon deposit and makes your vehicle's innards filthy.
