"Well, forget about those unimportant issues, shall we?" Tang Ziyi cut to the chase.
Receiving the three's attention, Tang Ziyi carried on, introducing the vehicles. "I suppose no one is interested that much in the vehicle's original specifications. Let's go to the modifications."
Even though Ling Qingyu had no ideas and nothing here was related to her, she was interested.
Back in her world, Ling Qingyu also had a curiosity for the police fleet and not much of the secrets among the modifications were known.
It was an opportunity to hear Tang Ziyi explain in detail.
Tang Ziyi walked up near the Jaguar saloon and opened the co-driver's door. "Come on. Hop inside. Let's start with the interior."
Seeing Tang Ziyi enter the vehicle, the rest of the girls followed suit. Yang Qingyue took the driver's seat; Ling Qingyu and Cai Ning naturally took the backseat while Ling Qingyu stayed directly behind Yang Qingyue.
Cai Ning narrowed her eyes and launched a piercing gaze. Ling Qingyu looked back nervously—if she was imagining Cai Ning making fun of her, not sure for the moment but her sixth sense spoke so.
"Jaguar Vehicle, sedan class, XF model." Tang Ziyi pointed out devices on the dashboard.
Pointing at the collective buttons with various numbers labeled, Tang Ziyi pressed one of them. Ling Qingyu reckoned these numbers represented codes used by the police.
According to Tang Ziyi's explanation, these were for the siren lights and sounds. Based on the user's choice, they could change the color of the lightbar and LED strobes—blue, yellow, red, or combinations.
Yang Qingyue pressed them, listening to Tang Ziyi's instruction. She could observe within the vehicle, lights flickering nonstop. Red, Blue, or a combination of both.
When she tried the sirens sound, a loud wail echoed across the hall. Tang Ziyi guided her to the buttons on the steering wheels.
"Initially, you know these buttons are for luxury purposes and after fixing these, you can change the tone, try it." Tang Ziyi said.
Yang Qingyue did as told, listening to wails changing to yelps, two tones and rumblers. Like a child having a new toy, she pressed everything.
Merely having siren functions had exceeded their police force in terms of wealth and equipment. Yang Qingyue shook her head in dismay.
"It's better to be LED lights than our conventional Halogen ones in the police force." Yang Qingyue sighed.
"It's true. Halogen causes unnecessary heating and can't be turned on for a long time. LED lights are simple and effective." Tang Ziyi voiced her thoughts. "Alright, let's go to the next one. This is the PED computer, which you can access to the police database."
PED—Portable Electronic Device
Tang Ziyi drew out the small folded laptop or tablets with keyboards already embedded inside the board; Ling Qingyu had no idea. Everything seemed so new as this was her first time to experience what was inside a police vehicle though these were her cars.
The PED didn't take up too much space, sufficient for the task. Even phone stands were fixed on the dashboard for the officers to put their equipment on.
Yang Qingyue's eyes brightened as if she had already seen the scenes her officers had easier access and saved time to complete the job.
Yang Qingyue nodded and got in. This time, Yang Qingyue and Cai Ning took the front seat.
After Ling Qingyu and Tang Ziyi sat in the backseat, Yang Qingyue pushed the start button.
"I almost forgot. It's not important but vital for officers on the scene when they left the vehicle." Tang Ziyi remembered the key important upgrade after seeing the ignition.
"If you stretch your hand underneath and a little further, you'll grasp some kind of key, which you'll pull it off when you park the police vehicles and allow the vehicles' function to turn on while you can go do your stuff without worrying someone stealing your vehicle."
Yang Qingyue tried and sensed a metallic structure. She pulled out the key and looked at Tang Ziyi, who nodded back. She tried to move gears or steering wheels. All failed without notions.
This key was the lock to allow the police officer to park with the car engine turned on without fearing someone would rob the vehicle.
"To be honest, the electronic button ignition method complicated this system. If it is a key ignition, simply press the locks and remove the keys. But the process is the same." Tang Ziyi added.
"I never knew there were so many complexities and puzzles hidden inside a simple police car." Ling Qingyu said while in deep thought.
A police car contained these secrets. What would the cars of secret units protecting VVIPs have?
Humans were capable of inventions nonstop. The most rhetorical fact was invention came from the idea of to kill one another and protect themselves.
"Now you know," Tang Ziyi patted her shoulders. Afterward, Tang Ziyi explained the remaining function provided by the car brand itself, receiving Yang Qingyue's complaint.
Cai didn't speak but her expression sent the same message.
"This is too classy and luxurious. Even massage is included?" Yang Qingyue was speechless. "Some consoles have unnecessary redundant functions."
Tang Ziyi shrugged. "I can't help; the fault lies with the automaker industry."
Tang Ziyi understood Yang Qingyue was referring to luxury content such as wireless charging, but she believed in the future police officers would rarely want other vehicles.
It's better to be rich than frugal. Police officers were also human and they had desires too.
Ling Qingyu watched the two policewomen tweak with the vehicles for a while until they began to drive out the way they came in.
Tang Ziyi didn't forget to describe the vehicles' remaining functions, such as a 360-degree monitoring camera to weave through congested space and a GPS system which was upgraded to connect with the police control center if needed.
In fact, Tang Ziyi could finish them and deliver the ready-made product but it was better for the police system to be handled by the police force itself.
Ling Qingyu advised the software which could simplify the police work and reduce unnecessary energy, promising she could come up with a product upon request.
Yang Qingyue and Cai Ning didn't express refusal to test out Ling Qingyu's mentioned integrated control system among their units.
They expressed wait-and-see attitude.
