What is happening: Tesla are struggling to produce and deliver enough cars to keep up with demand since they pushed to create a mass-market vehicle.
Sedan: After boosting production of their Model 3 Sedan, Tesla saw their Q4 deliveries more than triple.
Supply chain: These numbers still fell short of estimates though, as the car-maker struggled to get its supply chain working as efficiently as they had hoped.
Targets: Tesla had to scale back delivery estimates after a series of manufacturing issues. They were only able to meet internal production targets after opening up an extra tent-based make shift assembly line.
