JACKSONVILLE, Fla. – A 39-year-old man died and a 42-year-old woman was critically injured when their motorcycle was hit by a tractor-trailer late Thursday night on Interstate 95 northbound at Bowden Road. Florida Highway Patrol said the motorcycle was traveling at a slow speed when the driver changed lanes from the center lane to the outside lane directly in front of the semi. The big rig hit the rear of the motorcycle, causing the bike to flip, throwing the riders onto the outside lane of the highway. The crash report shows both the man and woman on the motorcycle were wearing helmets. The northbound lanes of I-95 reopened just after 4 a.m.

They were hoping Tesla's technology would mark an even bigger leap forward and propel the company's soaring stock to even greater heights. Musk raised those worries with a series of tweets Monday warning that Tesla's new battery technology might not be ready for high-volume production until 2022. Musk reiterated that timetable during Tuesday's showcase and then added it might take up to three years before the battery technology translates into a new Tesla model selling for $25,000. Besides lowering the price, Musk promised the new battery technology would help Tesla reduce the size of its vehicles by about 10% and extend their range by 56%. That projection implies the Tesla cars using the new batteries will be able to travel 500 miles (800 kilometers) or more on a single charge, surpassing the distance many gas-combustion cars can traverse before needing to refuel.
