That&#x27;d be a disaster on single-lane roads. Even with human trucks and their help (signalling if road is clear, driving on the shoulder when possible etc), it sucks to overtake them. If trucks were limited to 70km&#x2F;h, there&#x27;d be much more need to overtake them. Which would either cause either traffic congestion or more drivers doing reckless things. Let alone that non-driverless trucks&#x2F;buses&#x2F;campers&#x2F;etc would be stuck behind them forever.
