""A far better solution to transport and pollution than giant SUVs with horrendously expensive platinum catalytic converters burning exhaust from large combustion chambers which burn fuel inefficiently, is small vehicles with little lean burn engines without catalytic converters, which waste energy and don't even start working until they are warmed up, exacerbating pollution, especially in winter."" Or the "all electric" for about 70 percent of modern countries driving needs. siliconinvestor.com

"A far better solution to transport and pollution than giant SUVs with horrendously expensive platinum catalytic converters burning exhaust from large combustion chambers which burn fuel inefficiently, is small vehicles with little lean burn engines without catalytic converters, which waste energy and don't even start working until they are warmed up, exacerbating pollution, especially in winter." I believe Lean burn engines produce more Nox not less than conventional engines, so at least in the US one would not be able to do away with a catalytic converter: en.wikipedia.org indiacar.com ----The main drawback of lean burning is the large amount of NOx being generated, so a complex catalytic converter system is required---- "And, make roads electronically controlled, with proximity controls and automatic braking, accelerating and steering in vehicles to remove the human element in driving, and pack them closely together, at increased speed with increased safety and reduced fuel consumption. Not to mention variable tolls on roads in rush hours to control usage to free-flowing conditions at all times." There are many things we could do in the US to both reduce pollution and fuel usage, so far we are taking few steps to ameliorate the situation, depressing.
