The real reason Tesla may be giving free trials of its Full Self-Driving software

• Tesla is offering a free monthlong trial of its Full Self-Driving software.
• The driver-assist software is a $12,000 or $199 per month add-on.
• FSD adoption could significantly increase Tesla's profit margins and improve the software.

Tesla has launched a series of initiatives over the past week designed to promote its Full Self-Driving software — the effort could help increase adoption and improve the software in the long term.
