Social media posts have been popping up in recent days of Tesla owners trying out their car's new "Smart Summon" feature.

Rudy Giuliani confirmed on Tuesday that he has lawyered up, hiring attorney Jon Sale to represent him in House Democrats' impeachment inquiry into alleged efforts by him and President Trump to pressure the government of Ukraine to investigate Joe Biden.
The big picture: Sale is a former Watergate assistant special prosecutor and one of Giuliani's former law school classmates, per the New York Times' Maggie Haberman. Giuliani has been subpoenaed by the House Intelligence Committee to produce documents by Oct. 15. He has not yet stated whether he will cooperate. He said on Sunday that he would comply if Trump asked him to, but attacked Intelligence Chairman Adam Schiff as unqualified because he has "prejudged the case."
The Energy Department's Vehicle Technologies Office's "fact of the week" pulls data on 2 key categories of medium- and heavy-duty trucks to illustrate what prolific fuel users they are.
The big picture: As the chart above shows, in 2017 they consumed over one-fourth of the fuel used on U.S. roads despite being just 4.5% of the vehicles. "Combination" trucks alone — that is, tractor trailers — accounted for 17% of that consumption.
