Mechanic put in prison for selling 14000 truck emission bypass devices
A late model diesel truck capable of &quot;rolling coal&quot; almost certainly has an emissions defeat device or tune, or has otherwise been modified. These devices are not always about trying to extract the performance lost to emissions control. These larping ranchers also want to be able to produce thick black clouds because it&#x27;s funny to them to mess up someone&#x27;s day, possibly even their health. It&#x27;s a point of pride.<p>Hitting one of the sources of this technology is great. I just wish law enforcement would also go after the offenders buying them and using them on public roads as well. The unfortunate truth is I suspect the venn diagram of people who would buy this for the lolz and cops who have the same mentality has significant overlap.
