Vehicle identification and device communication through directional wireless signaling

A method, comprising:

• receiving, at a first user device system via a wireless communication link to a first vehicle, an identity token obtained via a wireless inter-vehicle communications system of the first vehicle, wherein the identity token identifies a second vehicle that is distinct from the first vehicle, and wherein the first user device system is distinct from the first vehicle and a first vehicle device of the first vehicle;
• determining, by the first user device system, and based on the identity token, a privacy preference for the second vehicle;
• generating an inter-vehicle message, by the first user device system, destined for the second vehicle, wherein the inter-vehicle message includes information specified in accordance with the privacy preference for the second vehicle;
• and
• the first user device system causing the inter-vehicle message to be transmitted to the second vehicle via the wireless communication link, wherein the inter-vehicle message is sent to the second vehicle via the wireless inter-vehicle communications system of the first vehicle.

A non-transitory computer-readable medium having stored thereon instructions executable by a user device system to cause the user device system to perform operations comprising:

• receiving, via a wireless communication link to a first vehicle, an identity token obtained via a wireless inter-vehicle communications system of the first vehicle, wherein the identity token identifies a second vehicle that is distinct from the first vehicle, and wherein the first user device system is distinct from the first vehicle and a first vehicle device of the first vehicle;
• determining, based on the identity token, a privacy preference for the second vehicle;
• generating an inter-vehicle message destined for the second vehicle, wherein the inter-vehicle message includes information specified in accordance with the privacy preference for the second vehicle;
• and
• causing the inter-vehicle message to be transmitted to the second vehicle via the wireless communication link, wherein the inter-vehicle message is sent to the second vehicle via the wireless inter-vehicle communications system of the first vehicle.

A user device system, comprising:

• a processor;
• a wireless communications unit;
• and
• a non-transitory computer-readable medium having stored thereon instructions that are executable to cause the system to perform operations comprising:
• receiving, via a wireless communication link to a first vehicle, an identity token obtained via a wireless inter-vehicle communications system of the first vehicle, wherein the identity token identifies a second vehicle that is distinct from the first vehicle, and wherein the first user device system is distinct from the first vehicle and a first vehicle device of the first vehicle;
• determining, based on the identity token, a privacy preference for the second vehicle, wherein the privacy preference includes a restriction on message content that may be transmitted to the second vehicle by the first vehicle;
• generating an inter-vehicle message destined for the second vehicle, wherein the inter-vehicle message includes information specified in accordance with the privacy preference for the second vehicle;
• and
• causing the inter-vehicle message to be transmitted to the second vehicle via the wireless communication link, wherein the inter-vehicle message is sent to the second vehicle via the wireless inter-vehicle communications system of the first vehicle.
