If you want to "rely on my rear-view mirror and head tracking for immersion" then for true immersion don't use a spotter. CC's warning that a faster class car is approaching is what you'd get IRL AFAIK.

Q: What kind of spotter calls do wec multi-class drivers receive during race
A: In multi-class endurance racing like the World Endurance Championship (WEC), spotter calls are crucial for both safety and strategy, especially given the significant speed differences between the various car classes (Hypercar, LMP2, and LMGT3). While traditional "spotters" in the NASCAR sense (someone watching the entire track from a high vantage point) are less common for the whole track in WEC, the role of "eyes in the sky" is performed by a combination of race engineers, team strategists, and in-car system
Here's a breakdown of the kind of "spotter calls" WEC multi-class drivers receive
1. Traffic Management (The Most Critical Aspect):
Faster Car Approaching/Overtaking: This is paramount for slower classes (LMP2, LMGT3). Drivers will be told:
"Hypercar [Car Number] closing, 5 seconds behind."
"Hypercar [Car Number] on your left/right."
"Clear left/right."
"Blue flag, faster car approaching." (While drivers are expected to be aware of blue flags, verbal confirmation helps).
Instructions on where to make way: "Hold your line, they'll go around." or "Lift slightly, give them room on the exit."
Slower Car Ahead/Being Overtaken: For faster classes (Hypercar, LMP2), drivers need to know:
"GT [Car Number] ahead, 2 seconds."
"GT [Car Number] in Turn 3, watch the braking zone."
"Be patient with the [class] car ahead."
"They're going to give you the inside/outside."
"Clear, good pass."
2. Situational Awareness:
Track Conditions:
"Oil/debris on track in Turn X."
"Wet patch at apex of Turn Y."
"Yellow flag ahead, sector Z." (Often accompanied by in-car warnings, but verbal confirmation is important).
"Safety Car/Full Course Yellow deployed."
Competitor Information:
"Competitor [Car Number] pitting this lap."
"Competitor [Car Number] running a different tire strategy."
"Your gap to [Car Number] is increasing/decreasing."
"They're faster/slower than you in sector 1."
Team Strategy Updates:
"Pit this lap for fuel and tires."
"Box, box, box."
"Push now, we need to make up time."
"Manage tires/fuel for the next X laps."
"Maintain gap to [Car Number]."
3. Car Status and Performance:
Mechanical Alerts:
"Check engine temps."
"Tire pressure low on front left." (Often automated, but reinforced verbally).
"We're seeing a slight vibration, monitor it."
Lap Times and Pace:
"Good lap, [time]."
"You're down 0.2 in sector 2, find some time there."
"Maintain current pace."
4. Driver-Specific Preferences:
The level of detail and frequency of communication can vary greatly depending on the driver's preference. Some drivers prefer constant updates, while others only want critical information. Spotters and race engineers often develop a personal "vernacular" with their drivers.
How it's communicated:
Two-way Radio: This is the primary method of communication between the pit wall (race engineer/strategist) and the driver.
Pit Boards: While less detailed than radio, pit boards are still used for crucial information like "PIT THIS LAP," "FUEL," or "BOX."
In-car Displays: Modern WEC cars have digital dashboards that display various information, including current lap times, gaps, and warning messages.
In essence, WEC multi-class drivers receive a constant stream of information designed to keep them aware of their surroundings, optimize their performance, and execute the team's strategy, all while navigating a track with cars of vastly different speeds. The "spotter" role is distributed among the team, with the race engineer acting as the central hub of information for the driver.
