With low-friction bearing and lubrication technology in place the potential threat to engine life by stop-start systems should theoretically be overcome.
Why do cars stop and then start again?
The widespread application of stop-start has only been possible because of improvements in things like battery technology, bearings, oils and control systems in vehicles. See, asking an engine to stop and then start again places strains on components.
